That is absolutely untrue. If you are the homeowner and the installer, you can install it yourself. It is no different than if you install or change an outlet yourself in your home. In any case, an insurance company will not void your coverage regardless, even if it DID cause the fire.

There is no doubt you can install an EVSE yourself but if you do not bother pulling a permit you are 100% liabable. Your insurance company will deny any claim god forbid there is a house fire even if the EVSE was not the cause.
