This law is intended to stop electricity from portable or permanent generators from accidentally entering and potentially harming utility company electrical systems. If you use a portable generator, you must disconnect your home or business from the utility's power by opening the main switch before connecting the generator. For permanent generators, you need to use a special switch called a double throw switch to ensure your electrical system is separated from the utility's system. Only generators approved to run simultaneously with utility power can bypass these rules.

If you're a manufacturer of electrical generators that can be connected to buildings, you must put a clear warning label on the generator and in the instruction manual about electrical hazards, like backfeeding into a utility system. This warning also needs to be in any ads for the generators.

Additionally, you can't sell or rent these generators unless they have the warning label visible on them.

This law requires that all public utilities inform their electric customers about the dangers of electrical backfeed when using portable and permanent generators. Additionally, if you own or use a generator and have it connected to your home's or business's electrical system, which is also linked to a public utility, you must inform the utility about where the generator is located.

This law states that if someone breaks the rules specified in Sections 119075 to 119085, they commit a misdemeanor. This can lead to a maximum fine of $500 or up to six months in jail. However, public agencies and their employees, as well as public utilities, are not considered 'persons' under this law, so they are excluded from these penalties.
