Using 30A GFCI Breaker backfed as main breaker for small panelboard

[jvacierto]

Hello, I have a 4 spot main lug only panelboard that does not have a main breaker slot and I want to use a 30A GFCI breaker (Murray/Siemens) as the main panelboard breaker. I know I can backfeed a regular 30A breaker to use as a main breaker per NEC, so can I do the same thing with a 30A GFCI breaker?

You cannot backfeed breakers that are marked with line and load.

I understand that, so if the 30A GFCI breaker is NOT marked with line and load, it should be okay to use it as the main breaker. Is that correct?

All GFCI breakers have marked LOAD terminals.

Thanks, that's what I was afraid of, so maybe I can talk our company into using a panel with a main breaker. Probably an uphill battle, but oh well.

If it's OK to use a panel with a main breaker which is non-GFCI what's the problem with using the main lug panel with a regular two pole 30 backfed? Why the GFCI??

Would a GFCI breaker even work if backfed? The receptacles wont.
