334.15 (Residential cabinets)

[Kimura]

I agree that 3/8" flex should be fine however if you read this (below) an inspector could turn it down. My personal opinion is where it says "where necessary" and inside the cabinet is not a place I would worry about

Thank you Dennis

Pulling 14/2 through 3/8 flex isn’t fun, but I’ve done it once before

Using 14-2 MC will save you a lot of labor.

May I presume 120v then?

Im sorry, yes 120v

BTW, will 14/2 even go inside 3/8" flex. We usually use 1/2" carflex and have never been turned down

My supervisor has asked me to spec a residential job for under cabinet lighting. I’ve located the power source from a lower floor. 1/2” EMT will pass up from lower floor, directly into lower part of kitchen cabinetry (into metal 4” JC)

The other cabinet I need to get to is inaccessible via the basement , so I’m planning on running 3/8” flex up through lower cabinet and across cabinetry above microwave (to get to other cabinets)

Per 334.15, flex should be sufficient for protection from physical damage. But getting conflicting answers.

Thoughts?

Hi Larry. 14/2 inside

[LarryFine]

Are we talking 120v lighting or low-voltage?

What are you considering putting in the 3/8"?
