I'm in England at present, but can someone help by describing the process for becoming a Licensed Electrician in the United States?

Specifically, is there is a training standard, or certificate, for Level 4 Electrical Safety Training (working on or near parts energized at over 600 volts)?

OSHA 29 CFR 1910.332 defines what type of training is required generally for electrical work but does not explain how it is organised, controlled or certified nationally.

Thanks very much, David
