First, Happy Easter to all who celebrate this day.
This is the third of the top ten Code changes because it will cause your inspection to fail if it is not done. Our top ten Code changes have no importance of order whether 3rd or 10th they are all just what I feel should be on your top ten list of changes to know.
During the last couple of months while doing inspection one new Code change that has been overlooked is 408.4(B). The identification of where the feed to a panel or switchboard comes from. This new requirement will help the electrician who has to service the panel or make some changes to the circuitry, find where the main source is and turn it off. I find electricians working on panels without turning it off because they can’t find the main, which puts them at risk.
This is a good change to the code and should create a safer environment for the service electrician. A detailed label will help the future worker know where the disconnect is and keep them from working it HOT. This does not apply to one and two family dwelling units.
Till next time work safe be safe
