It is vital that you connect your appliances to an extension cord because you cannot directly connect them to the generator. There are many types of extension cords, and some of them may not be compatible with your generator. Make sure that you choose the right cord to avoid damaging your appliances.

Do You Have To Turn Off Your Main Breaker When Using A Generator?

Yes, never forget to switch off your main breaker. Before starting up your generator, turn on your fuel valve first. Let your generator warm up before turning on your circuit breaker again. 

What Should You Not Run On A Generator?

It would be best if you never connected the generator via a back feed. This wrong method is when you plug your generator into a wall outlet. This action is risky and can bypass some built-in household circuit protection devices.

Turn it off before refueling your generator and let it cool down first. If you add fuel while the generator is still hot, it might cause ignition.

Where Do You Store Gas For A Generator?

Store your fuel tanks in a shed or garage that is well-ventilated. Do not place it in direct sunlight and other sources of heat.
