Generator Label

[Jerry Simon]

I don't understand why the gas main would need to be turned off?  (So the gas-fired generator won't accidentally turn-on when messing with the panel?)

[Les]

yes

Makes sense.

In case you think that turning off the main breaker means that the panel is dead. The sensor that tells the generator that the utility source is dead may be connected to the panel itself instead of upstream of the main disconnect.
