How To Safely Operate A Portable Generator Come Rain, Snow Or Rain (1)
It could be that you are one of those people who feel that they have no other choice.In humid weather, use a portable generator. If not, have you thought about what happens if you're hiking or camping in an RV park or racetrack and suddenly the power goes out in the middle of the party? Are you ready to run your portable generator or inverter in such a humid climate? of courseit would not be recommended. In some situationsit can even be catastrophic.

Obviously, most people know that it is quite dangerous.Use a portable generator in a garageor very close to an open window. Ideally, as manufacturers advise, aThe generator should always be at least 10 feet awayfrom home. This limits the risk of CO poisoning. As Joseph Mohorovic, an expert on the subject, recently said:It is never safe to run a generator in the garage., regardless of whether thethe door is left open or not. HeThe risk of CO poisoning remainsreal in such a situation.

How To Safely Operate A Portable Generator Come Rain, Snow Or Rain (2)The question arises, why is it not advisable to use a portable generator in humid weather? The reason is simple - there is a risk of water getting into the outlets. In fact, if the electrical panel gets wet, there is a risk of damaging the generator. What's worse, the risk of electrocution is high.

For the most part, many portable generators usually have what is called a GFCI. This means that the residual current protection outputs are interrupted. As soon as these plugs get wet, they automatically turn off. Of course, anyone approaching the generator at that time would be instantly electrocuted.

How To Safely Operate A Portable Generator Come Rain, Snow Or Rain (3)As the Honda product manual specifically states, a portable generator, no matter how small, can produce enough current to inflict a severe shock and, in the worst case, electrocution. It is very important to check all the electrical components of the panel before using it. And it is especially advisable to check this and the GFCI when the portable generator is not protected from the weather and is stored outside.

Also, attempting to use your generator or any electrical device in the snow, rain, near a puddle of water, or near a sprinkler system can be very dangerous. Even getting your hands wet can cause an instant electric shock. Because of this, it is always important to keep the generator as dry as possible. So how can you stay safe? Consider the 10 security tips listed below.

10 Tips for Using a Portable Generator Safely

Interestingly, trends show that despite the many warnings issued by manufacturers, many generator users ignore safety warnings, resulting in frequent injuries and deaths. The following tips can help you avoid such unnecessary disasters and save lives.

Stay away from generator damage and electric shock.

Never run your generator in wet weather unless you use a generator tent.Remember that light and water do not mix. If this happens, it will damage the generator and possibly electrocute people. This happens because water gets into the breaker panel or sockets and shorts out the frame.

This is especially true since most portable generators are grounded on their frames. This situation causes the static charge of the metallic sections. Plugging or unplugging a wet generator can kill. This will result in a strong arc that can cause injury or death.

Never run a generator in a garage or indoors

It doesn't matter if you left the doors open. Never do this. The consequences can be devastating. May cause CO poisoning. If you want to use the generator, go outside, at least 20 feet from the nearest building. Remember that carbon monoxide is an instant killer. Carbon monoxide is colorless and odorless and is heavier than air, making it more deadly. Because of this, this killer gas has the ability to quickly build up and build up anywhere.

As mentioned above, simply opening the garage door does not guarantee that CO will leave the garage. Conversely, if the wind actually blows in, it could cause the deadly gas to blow right into your home. It simply spreads through openings in doors or window seals. Even if the garage or shed is a bit far away, keep in mind that CO can remain in the area for many hours.

deadly fumes

To illustrate, you can enter the garage a few hours later to refuel the engine. Even then, you may still be overwhelmed by the deadly fumes, as they would still be present in large numbers regardless of timing. Interestingly, research shows that CO levels from portable generators are 1,500 times higher than those from today's vehicle engines! Therefore, it is advisable to always place the generator outdoors and away from habitable buildings.

In fact, most open frame generators emit heat at all four corners. Also, enclosing the generator will reduce its lifespan as the machine will always run too hot. Avoid using flammable materials or materials that can melt. This can easily cause serious injury or fire.

Always use one hand when touching the generator.

This is advisable as it helps prevent the formation of the circulatory system throughout the body. Be sure to always wear rubber soled shoes when handling the generator. Never help electrical currents move to the wrong places. Our body is such a place. When approaching a running generator, always touch metal surfaces with one hand. As mentioned above, wear rubber-soled shoes. This is especially true when the floor is wet. As a general rule, electricity always flows along the path of least resistance. if you're not carefulthis can be your body!

Never use the generator in hurricanes or adverse weather:

We all know the damage that cyclones, hurricanes or tornadoes can cause. ParticularlyIf the speed is between 60 and 70 mps, it can be devastating.. At such times, heavy objects can be carried. If you try to use your generator in such harsh conditions, the result can be disastrous. For one, the generator can swing from side to side and even be dragged. Why not wait for the wind to die down before trying this? It won't cost you much compared to the potential damage if you try to run the machine in inclement weather.

Avoid standing on the hot muffler when refueling:

It's good to know what part of the gasoline ignites the vapors; these are the small drops of gasoline. They mix with air and produce vapors. Always allow the muffler to cool down for at least 10 minutes before refueling. Of course, never try to stand on the side of the hot muffler while refueling. This can be deadly.

Avoid fuel clogging

Be sure to always close the fuel valve. Always run the generator until it shuts off automatically. This ensures that fuel does not clog theinjectors or carburetors. If you want to store the generator for a long time,use new fuel. You should also use a fuel stabilizer. Remember that every time you need to use your generator you want it to start immediately and without problems.

As this may not be practical, try closing the fuel supply valve. In this way, you can run the injectors or the carburettor dry. After that, you will know that the generator is dry when it automatically shuts off. You can then put a fuel stabilizer in the tank. Don't forget to run the generator at least once every three months. These steps can help you reduce generator starting problems in the future.

Turn off the main breaker before starting your generator

It is very important to do this. Once the generator starts and is idle, you can now turn on the main breaker. Most of the generators that have come on the market recently have a main on/off switch. Always make sure the breaker is off before turning the generator on or off. This should also be the case when you connect or disconnect the wires found on the alternator panel.

The advantage of this is that the generator is always ready to take the load, while ensuring your own safety. Make sure all your electrical equipment is protected from damage when the generator starts or shuts down. It is good to be careful since the electricity generated at these times can have amperage or voltage spikes. These can be dangerous, so caution is advised.

prevent flooding

In either case, avoid locating the generator in an area prone to flooding. This is, of course, a matter of common sense. If the water level rises during flooding, this endangers your own safety and the machine may also be damaged.

Use a transfer switch for backup:

A transfer switch helps draw power from the generator by isolating the necessary circuits. This ensures that power is not fed back to its immediate source, i.e. power lines. If the power backfeeds, it can mean instant death for line workers. The switch also ensures that the generator is not overloaded and therefore works effectively.

steel box

How To Safely Operate A Portable Generator Come Rain, Snow Or Rain (8)A good way to keep your generator running in a safe condition is to use steel casings. To make sure your generator doesn't overheat, you can use vents liberally. However, only some generators are tuned to it. Not all machines fit in these cases. Remember that good steel boxes need to be professionally installed. A proper base for mounting the case is also important.

This is a special plastic shed. The starting price for one of these is usually around $400. They often come with an additional shelter, which is around $949 starting price. It's worth remembering that for the above reasons, manufacturers caution against including portable generators. Therefore, it is important to be careful with these types of items.

How To Safely Operate A Portable Generator Come Rain, Snow Or Rain (10)Pop-up roofs are not the most practical consideration when it comes to protecting your generator set. Therefore, they cannot protect sensitive outlets from driving rain. They can also be easily damaged by winds over 20 km/h. They are also difficult to anchor, especially in driveways. They range in price from around $75 to over $300 depending on the frame and quality of fabric you want.

Generator covers:

How To Safely Operate A Portable Generator Come Rain, Snow Or Rain (11)As mentioned above, it is generally not safe to run generators in rain, snow, or wet weather. Is there any way to avoid this? Luckily yes. You can buy a good quality alternator cover. A good cover will protect the generator from the elements. At the same time, you can still safely operate it. You can waterproof and protect places on the machine where you don't want to get wet.

Pretty cool, the special cover still allows the generator to be portable. You can easily and quickly install it, or even transport it to different places. Some of these covers even encourage natural cooling. Some are suitable during a blizzard or hurricane, although as mentioned above this is dangerous in inclement weather.

The elements

Make sure that the most sensitive parts of the machine are 100% well protected. This includes outlets. Make sure there is some airflow to prevent overheating. Wondering if my new enclosure can withstand high winds and the elements? It is portable? If the answer is yes, then you are safe.

However, in the end the question arises: How can I build such a case for my machine? What materials do I need exactly for such a project?

DIY case for portable generator

Project requirements:

You need a few things to build a good case for your generator. This includes the following 9 points:

  1. measuring tape
  2. Aluminum sheet
  3. cheap air vents
  4. Carpenter's pencil
  5. Puzzle
  6. ½ and ¼ machine screws
  7. caulk
  8. railing
  9. some plywood

Now that you've assembled all the required parts, it's time to begin the actual construction of your generator housing. How do you proceed? Just follow these steps methodically.

  1. Design Case:

The first thing to do is to have a sketch of the type of enclosure you want to build, its shape, size and structure. In this sketch, be sure to position the features exactly how you want them. This will also let you know what type of material you need and how much. Remember that the casing must not only be protected from rain, but also allow air to enter the engine.

At the same time, the heat from the generator and the exhaust air must have an outlet space. This keeps the machine running efficiently and also takes care of safety issues. On the sketch, mark the locations of such important items as the surveillance system, cooling fans, vents, exhaust, and other cooling items. Leave a 2-3 inch gap to separate the generator bypass box from the generator.

  1. Platte Obere

Use a saw to cut the plywood. This makes it match the overall dimensions at the top overall. It also lines up with all the other supplements already introduced. Then the front and side panels are attached to the top panel. You now need to measure and cut the 20.5-inch railing bars. Make sure your dimensions match the dimensions of the top panel. Just cut two more of them to the required width. However, make them a bit shorter. Next, use the 1" desk screws to attach the railing rods to the top panel. The latter will further help you attach the remaining panels so they flush with the top.

  1. frontal y lateral

What is the front panel? It is the panel that is placed around the air intake of the engine. Finally, in a further step of this process, the rear wall itself is built. Interestingly, both the front and side panels are built similarly. Using front and side measurements, you now need to cut three pieces of plywood. Then measure the blinds to determine your correct size. Then use the carpenter's pencil to mark the rectangular outline.

Remember that the vents are very important to allow air to circulate inside the chamber when the generator is running. Now cut the slots with the jigsaw. You can also drill holes in the outline and cut it out with the dremel. Make sure you cut it clean and straight so it looks good. Finally, attach the vents to the side panels with the ½-inch screws.

  1. Rear wall construction.

This is usually done a little differently than the others. The intricacies and intricacies of the exhaust system demand it. Make sure you don't compromise on functionality just to protect yourself from the rain. Make sure the ventilation is absolutely free of obstructions. Exhaust gas buildup can damage the generator.

Remember that the back piece should be a little less than half the measurement of the front piece. The remaining space is usually occupied by the aluminum sheet. The sheet metal should only be slightly larger than the wood on the back wall..

  1. fix the leaves

At this point, use the ¼-inch machine screws to attach the aluminum sheet to the back of the panel. The largest panel acts as a canopy, protecting the generator from damage. It can also be bent to allow exhaust gases to escape.

  1. Mount the panels

How to assemble the panels? Follow these simple suggestions:

  • Use the 1" table screws to attach four of the panels to the rails. Set all the edges square. To do this, use the L-brackets. For each corner, you should use two of these brackets.
  • Seal the caulk for porous edges. You can use carpenter's glue. However, this may be too tight if you need to adjust the layout later. At this point, the case can be judged.
  • Wrap bungee cords around the generator. This will prevent the box from being blown away by very strong winds.
  • Change the impact box. The already created design is like a cover that is put on the generator. Add a palette to the bottom panel. Pay attention to the wheels of the generator.

The generator is probably now fully covered. Later, you can equip the baffle box with additional functions of your choice. This may include an attic vent, an exhaust system, fiber optic installation, a cooling fan, a temperature controller, and insulation.


Why let snow, rain, or inclement weather keep you from enjoying the convenience of your generator when camping remotely? Just build a nice case for your portable generator and make sure it can act as a generator baffle box alternatively. If it's good for you, make sure the case also allows you to control the temperature while limiting noise levels. Use the tips above to enjoy the exciting generator experience, rain, shine or bad weather. Do you have any other ideas on how to make this even better?
