Full Size EGC

[mbrooke]

Anyone do full size EGCs for circuits up to 60 amps?

Only with a cord or cable that comes that way; otherwise, it's #10.

Does that flex connector have an insulator? I don't see one in the inspection window.

Nope. Code article?

Looks like FMC so no anit-short device is required.

What you never size your EGCs to Table 54.3?

Good to know

Without know the circuit ampacity no one can say for sure if the EGC in the photo is larger than required or not. A 30 amp receptacle would have a full size EGC even if the ungrounded conductors were #6 AWG.

Some hot tubs require a full sized egc.

Which I never install!
#10 is sufficient!

Well, I suspect you will end up in hell....

Perhaps 110.3B. Although in Art 348 it just says trim the ends of the FMC. But the hole in the fitting is to see if the end insulator has been installed.
I always used the plastic insert bushings.

I follow the general rule that field-installed conductors need to be bushed, factory-installed don't.

Then there's AC/BX.

50 amp circuit.

Do you know why that is?

Is it though?

When the raceway itself is a qualifying EGC, such as EMT, I do not use a wire EGC at all (unless outside).

True, though IMO a wire EGC is more reliable. IMO

Interesting. I feel that the raceway is more reliable.

Until it becomes disconnected.
