What do you see? Kennedy stay out of this one since you brought it to my attention!
No, that is not an issue. It is something visible inside the open disconnect enclosure.JAC said:not much on electrical knowledge so I will take a shot. The cans are not bonded together due to the PVC conduit :?: :?
Can't honestly say that I know the answer. This was already inspected and approved by someone else. I was there for another reason and popped the cover(with approval) for a photo op for training.chris kennedy said:Can't stay out of it, I think I see another problem. Was the lug in the bottom right of the enclosure that is attached to the enclosure field installed? Is there paint under it? 250.12.
Yeah I caught the bushing in my previous post. What I thought was cut of is the mounting screw. My monitor ain't too sharp this morning.raider1 said:Try 352.46 and 300.4(G).Chris
250.30 is for separately derived systems. I believe the correct reference for this service would be 250.24(B), which is very similar to the section you referenced. Both of those sections require the grounded conductor (neutral) to be connected to the service disconnect enclosure and the equipment grounding conductors. This is to be accomplished by the main bonding jumper. In the photo, I believe I can see the head of the main bonding jumper (a green screw) in the right side of the neutral bar just above the lug containing the grounding electrode conductor. That screw connects the grounded conductors to the metal enclosure, an through the enclosure to the equipment grounding lug (if the paint has been removed under the lug as Chris Kennedy mentioned).BigDave said:Shouldn't the EGC in the open panel be bonded to the grounded conductor lug, since it is the first system disconnecting means as per NEC 250.30 (A)(1)?
Welcome to the BB. CT means current transformer. Here is a picture of CT's installed in a CT can.BigDave said:As a matter of fact, I had the same question about CT, as in CT can, in one of the other topics.
A #8 or smaller copper grounding electrode conductor must be installed in a raceway or cable armor.Pcinspector1 said:The copper ground wire exiting the disconnect should be protected in conduit.
