Love Junction Boxes


Just finished getting my lights in the crawl space wired up....

I installed a junction box in the crawl space.....I have a conduit that runs from my load center under the family room slab to the crawl space next to it....from the junction box I have another conduit that goes to the existing house....then another juntion/pull box where it goes up to the attic and then connects to the existing wiring.

Anyway....in this box I have some terminal blocks which are being fed from the load center via my 'utility' (GFIC) breaker....this utility power is for my lights and a few outlets under the house (crawl space) and around the outside of the house.

Anyway...this junction box is a great way to help pull wire and give me a way to add stuff in the future.

Just remember to consider the derating issues from all those conductors in one conduit.

You are also supposed to identify which neutral goes with each hot.

Metal box on PVC conduit is required to be grounded/bonded. Needs a bonding jumper from one of those ground wires.

Yea....I knew that (but forgot)....thanks for the reminder....I'm somewhat spoiled by using AB terminal blocks...the grounding ones actually bit into the DIN rail providing the ground....there Enterlects' don't do that...so I will need to run a ground.
