Any 6b inspectors here with the correct answer?


Have an inspection coming up on Tuesday for a single elevator pit and machine room

Question is:
Does the Sump pump in the pit require a gfci?
620.24 makes no mention of a gfci.
I say yes to a gfci , Others said no, and use a single outlet.

Also I Don't have The current ASME book with reference to ASME A17.1-2004 regarding illumination levels. We installed 3 -4' WP florescent wraps

Any opinions?

Found Answer 620.85

tried to edit previous post

620.85 Ground-Fault Circuit-Interrupter Protection for
Personnel. Each 125-volt, single-phase, 15- and 20-ampere
receptacle installed in pits, in hoist ways, on elevator car
tops, and in escalator and moving walk well ways shall be
of the ground-fault circuit-interrupter type.
All 125-volt, single-phase, 15- and 20-ampere receptacles
installed in machine rooms and machinery spaces
shall have ground-fault circuit-interrupter protection for
personnel.
A single receptacle supplying a permanently installed
sump pump shall not require ground-fault circuit interrupter
protection

Pays to read though all of 620 first

All passed Almost......

Inspector tried to knock me down with

620.51 (A)
(A) Type. The disconnecting means shall be an enclosed
externally operable fused motor circuit switch or circuit
breaker capable of being locked in the open position. The
provision for locking or adding a lock to the disconnecting
means shall be installed on or at the switch or circuit
breaker used as the disconnecting means and shall remain
in place with or without the lock installed. Portable means
for adding a lock to the switch or circuit breaker shall not
be permitted as the means required to be installed at and
remain with the equipment

Job specs from Manufacturer were for a Nema 3 100-amp SR shunt breaker
No problem we use G.E.
Inspector wanted a lockable main and did not want to accept the hinged cover lock
as the permanent means also that the hinged cover was in the dedicated working space, i knew it was going to be a battle of wits

My fight was the the lock was "ON" the disconnect means and did not need to be on the breaker or switch, He said that the disconnect was considered an enclosure., Told him go read the definitions of both. well he made a few calls and i won

I then asked if he ever saw a Nema 3 disconnect in that type of breaker lock.
got no answer, I know a nema 1 does

Was i correct in backing him down before he pulled AHJ card on me?

We then we got into 620.85 for my gfci on the sump
code said "shall not require" I believe that my addition of a gfi was above code
"he said you install a gfi in this state you fail" Well i rolled over on that one a gave him his single outlet, made him happy
 
You did good. I disagree with your design choice about the GFCI, but the AHJ had nothing backing him up in making you remove it. It's disappointing when people can't understand 90.5. :(
 
lol Thank you
as for the sump outlet, I knew better.
My own home has a perimeter drain that dumps to a tank with a pump outside
NO gfi there or the one in the garage fridge

Now, those I stand behind. Splitters are cheap and defeat the single recep in a heartbeat.

As for the sump in the pit, it's unlikely to see that kind of use; and it's not something someone is going to wander past and notice a tripped GFCI until there is a bigger problem. I'd rather take my chances without the GFCI protection on that and maintain a better probability of a dry floor down the road.
