210.8B GFCI and commercial kitchens and water heaters

[dm9289]

In looking thru code mostly 210.8B and 422 I have some confusion about GFCI protection

It seems to basically say all things in a commercial kitchen. Would a walk-in cooler be part of a commercial kitchen? As i read I imagine a typical residential fridge in residential no GFCI but same fridge in commercial probably yes.

Or would a residential or commercial hot water tank require GFCI protection? I can see no requirement. I believe it needs GFCI but I cannot find in code

If they are direct wired then no gfci is necessary.

(B) Other Than Dwelling Units.

All 125-volt through 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to ground, 50 amperes or less, and all receptacles supplied by three-phase branch circuits rated 150 volts or less to ground, 100 amperes or less, installed in the locations specified in 210.8(B)(1) through (B)(12) shall have ground-fault circuit-interrupter protection for personnel.

I agree.

Key word being "Receptacles".

HMMMMM! So if no receptacle and direct wired no GFCI breaker either

Thats odd to me seems like a safety work around cause am I correct in assuming same hazards exist.

I believe the reason for the receptacles to be gfci protected is because of their tendency to break down and loosen up connections, especially the ground. Less likely to happen with a direct wire

And, if you mention the word "outlet" and GFI in the same sentence around here it's going to cause a storm of responses...

Makes more sense now

You are correct as usual sorry GFCI receptacle lol. The verbiage is important.

I believe another concern is kitchen personnel handling plugs in a potentially wet environment.

Yep did it many times 30 years ago when i worked in food service

They often move equipment for cleaning, and if they move them farther than the cord allows, they have to unplug them. That's one of the reasons for the GFCI.
