4 wire plug from 100A main panel

[bitteritdown]

Does the following diagram represent the correct way to wire a 4 wire 50amp plug from a 100 amp main panel off a 50 amp breaker?

Ground and neutral are bonded at main. What must be changed if anything? Does it need a separate ground rod?

A GFCI breaker will have an auxiliary neutral attached to the breaker. That needs to be connected to ground bus bar. No extra ground rod required unless you are running a permanent sub panel.

Thanks for reminding me about the aux neutral on a GFCI breaker. No sub panel this time, just a 4 wire 50 amp outlet direct to the main 100 amp service panel.

no additional ground rod required, even if coming off a sub inside the residence. only time you really get into that is if you are building a brewery in an external building and will have a sub panel in there. there are exceptions, of course, but in general, no need for an additional ground rod if staying within the house.
