Portable generators are one of Aussies' go-to power sources for outdoor adventures. However, is it okay to run a generator in the rain? Can a generator get wet when not in use or during operation? Read on to find out everything you need to know about running your unit in wet weather.
The answer here would be yes and no. Yes, you can run your generator in the rain as long as you keep it safe from moisture, especially the sockets for electrical safety.
However, it is not advisable to let your generator get wet, whether running or not. For safety reasons, no indoor or outdoor power equipment should be mixed with water. There might be mentions of rain-safe generators, but experts still highly recommend keeping any unit dry to prevent accidents like electrical shocks.
However, there are certain levels where different generators can withstand moisture in case it gets wet. Read on to learn more about this and check how durable your unit is when exposed to water!
Waterproof Levels for Portable Generators
There are no 100% waterproof power sources, but there are specific levels at which portable generators are protected from moisture. These are called IP ratings and usually come in two numbers. The first digit refers to the level of protection the equipment has against solid foreign objects, while the second number corresponds to its waterproof rating.
Solid Foreign Objects
0 – No protection provided
1 – Protected against solid objects larger than 50 mm
2 – Protected against solid objects larger than 12.5 mm
3 – Protected against solid objects larger than 2.5 mm
4 – Protected against solid objects larger than 1.0 mm
5 – Protection against dust (limited ingress allowed)
6 – Completely dust-tight
Liquids
0 – No protection provided
1 – Protection against vertically falling water droplets
2 – Protection against water droplets falling at up to a 15° angle
3 – Protection against water spray
4 – Protection against water splashes
5 – Protection against water jets
6 – Protection against strong water jets
7 – Protection against temporary immersion in water
8 – Protection against continuous immersion in water
9 – Protection against high-pressure, high-temperature water jets
At Outbax, our inverter generators have sockets with an IP54 rating, making them safe from dust and water splashes.
This doesn't mean you can be complacent about where to put your unit, though. Part of good generator maintenance includes keeping them away from areas where they might get wet and providing an additional layer of protection to keep them safe from moisture, like generator covers.
Generator Safety 101: Protecting Your Unit From Getting Wet
There are tons of generator covers for outside while running your unit that you can go for. You can pick them according to size, portability, and level of protection. Here are some ways to keep your camping generator protected while enjoying the great outdoors.
Canopy/Tent covers
Canopy or tent-like covers are affordable, effective, and easy to pack on any outdoor adventure. These can be bought as an accessory in most generator stores. The great thing about canopies is that they protect the unit from rain and snow while still allowing maximum generator ventilation.
Airflow is crucial for carbon monoxide safety when using generators. Just remember, if you're going for a canopy generator cover, keep it away from the engine's exhaust so it doesn't melt or catch on fire. You also want to avoid tight-fitting covers as they're great for protecting while it's in storage but is not advisable for use while your generator is running.
Generator enclosures
If you have RVs or cars, a solid generator enclosure would also do a good job of keeping your generator safe. You can even have this custom-made for the perfect fit, all while keeping the ports accessible.
Generator enclosures are like cases in which you can house your unit. They come in different materials but can be hard to pack if you're not taking a vehicle.
Another benefit of enclosures is that they help tone down your unit's noise. Some areas have generator noise ordinances, and having a sturdy case for your portable power station will reduce the noise it makes while running and allow for a peaceful camping experience.
Looking for an extra quiet unit? Go for inverter generators, preferably those with an average of 58dB noise level. Unlike bulky standby generators with a blaring noise, these ultra-portable units are more discreet and perfect for home or outdoor use.
Using Your Generator in Wet Conditions
Rainy seasons are perhaps one of the most crucial times you would need a generator. They're one of the best temporary power solutions in the market and are extremely handy. The question is, how are you going to run them properly in wet conditions? Let's start with the basics first.
Number one, there are no absolutely weather-resistant generators but no matter how rainy it is, that's not a reason to use yours indoors! It's still best to run them outside with a cover and follow the standard rules of outdoor power placement. For generators in particular, here are some guidelines you need to remember:
- Place your generator on a flat surface outside that doesn't collect water. Never try to run your generator inside your house!
- Carbon monoxide poisoning can happen in as little as 5 minutes. Run your generator at least 10 feet from your house (20 feet away from any doors, windows or air intakes).
- Don't put a generator under an overhang, in a breezeway or in areas where snow drifts can occur.
- Don't place a generator near flammable materials or fuel.
What about running a generator during a storm? Well, it certainly helps a lot with storm preparedness especially during power outages, but you should never run a generator under extreme weather conditions. Keep your emergency power source dry. If you don’t have a special place for it, protect it from water, like rain, snow, or flooding.
Now, onto regulations or outdoor power laws required when using generators in wet conditions. Since rainy seasons mean extra risks for generator users, below are some of the safety standards required for those who are running their units in the rain:
Australian Safety Standards
AS/NZS 3010:2017
This safety standard discusses safety guidelines for safe generator usage and installation, including in wet conditions. It requires generators to be installed and operated in a way that allows for minimal risk of electric shock, especially in damp environments.
AS/NZS 3000:2018
Also referred to as "wiring rules," this standard mandates the importance of safe installation of electrical equipment, including generators.
Generator Placement
Weather-proof generators sound great, but unfortunately, these handy backup electricity sources need to be safe from the rain. This is where generator covers come in handy. Make sure to use covers and place your unit on a flat surface. This will prevent water from collecting and damaging the electrical connections.
Grounding Requirements
Proper grounding is a mandatory part of portable generator regulations, especially in wet conditions. Grounding requirements should be in accordance with Australian standards and may vary depending on your generator type.
Another thing to consider would be the use of Residual Current Devices (RCDs). These are crucial when operating your generator in wet environments as it increases protection against electrocution.
Usage and Maintenance
Make sure to stick to the manufacturer's guidelines when using your generator on a rainy day. Follow these rules for using weather-resistant covers, ensuring good airflow, and regularly maintaining your unit. Keeping thorough records of generator maintenance and inspections is typically necessary to meet regulatory and standard compliance.
Inspection and Troubleshooting
Regular inspections are required to ensure that generators and associated electrical connections remain in safe working order, especially after exposure to wet conditions.
Last but definitely not least, regular inspections are ideal, but under no circumstances should you do DIY electrical work. Only licensed professionals should modify or install connections, especially in wet conditions, for maximum electrical safety.
What If Your Generator Gets Wet?
If your generator gets wet, follow these safety steps and handle your unit with care.
Turn off the generator immediately.
Switch off your unit right away. Do not touch the generator or its components if they are wet while operating.
