Default Elevators

I have 8 elevators on my job. Section 38-024(1) of the CEC says a separate branch circuit for an elevator pit. Is this interpreted as 1 cct.per pit? Engineers drawings show a group of 4 pits with 4 of the receptacles on one branch cct. and all 4 pit lights sharing another cct. I interpret this rule as 1 lighting cct and 1 receptacle cct. per pit.

Are you the Licenced electrician or an apprentice? I cannot tell from your profile because it hasn't been filled out...



It says separate branch circuit for an elevator pit... the way that you are interpreting it, for your 8 pits, you'll need 16 circuits... as MikeFL said, what did the engineer say?

16 circuits for 8 elevator pits? Man, I hope you're installing 1500 watt lights in each pit... Call the Engineer or ask your boss...

In the NEC the pit light can’t be on the same circuit as the pit receptacle. Usually three circuits when you add in the sump pump. Maybe CEC is similar?

I don’t think we have a code on limiting the separate circuits to one pit. So lighting would share a circuit, receptacle would Share a circuit and pumps would have dedicated circuits. Your sealed drawings seem to follow our code rules. I would just follow the drawings.

The machine room also gets its own receptacle circuit.

Is it a common pit or individual shafts?

All I know about elevators is that elevator inspectors are free to write their own rules and electrical code is meaningless to them.

I would think that if the NEC intended a separate circuit for each pit was required, then it would use the term, " Individual" branch circuit or "dedicated". I know the intent is not to have the receptacle and light together so that the service worker is not in the dark if he trips out the breaker while using the receptacle.
I concur with the previous comment, Ask the engineer.

I had one tell me over and over that a pit is a wet location.

But when I asked what makes it a wet location , he said the pit makes it one and that I had to use raintight fittings and in use covers.

I asked him if he’d seen sumps in a basement of dwellings, he said yes but those are different.
