First, on a project I have going on with panel lighting, the electrician is saying that all of the lighting circuits must us a GFCI protected circuit breaker. This is in an area that uses the 2014 National Electrical Code. I see no references to this requirement anywhere. Does this make any sense?
My second question has to do with combining the panel lighting with a house with a back-up generator. What is the maximum frequency variation Control4 allows from transfer time to steady state operation? The generator vendor is stating the following:
"Steady-state means that the load on the genset is not changing - that load could be 0%, 25%, 50%, 100%, etc. The key is that the load is constant. For all of those constant-load conditions, the frequency will not deviate by more than +/-1% ? for a 60Hz machine, the frequency will always be between 59.4 and 60.6 Hz.
For a start-up and transient event, there will be a larger frequency dip (or overshoot for unloading). We also do testing for this at various load steps (25%, 50%, 100%, etc.) and according to ISO 8528-5. The allowable frequency dip depends on the G-level desired but can be as high as 15% (or 18% for overshoot)."
Will this cause any issues and if so, how should they be addressed.

I actually have two questions.
First, on a project I have going on with panel lighting, the electrician is saying that all of the lighting circuits must us a GFCI protected circuit breaker. This is in an area that uses the 2014 National Electrical Code. I see no references to this requirement anywhere. Does this make any sense?

Thanks for the help
