Name That Violation - Generator Situation

[jar546]

This generator was replaced, and we were supposed to reconnect the new one, but there was a problem when we got there and saw the existing wires in the conduit. I will give you that much of a clue. Look at the wires. This is not an issue of wires that are too long or too short. It is something obvious. What do you see, or what don't you see? I did this job with @chris kennedy about 7 years ago while waiting for my inspector licenses to be transferred and approved in Florida.

Not the obvious section we are looking for. The conduit is not reconnected yet so.....too early.

Not the main issue. Not connected yet.

Lack of a bonding jumper around the FMC?

310.8 Marking.
(A) Required Information. All conductors and cables shall be
marked to indicate the following information, using the applicable
method described in 310.S(B):
(1) The maximum rated voltage.
(2) The proper type letter or letters for the type of wire or cable
as specified elsewhere in this Code.
(3) The manufacturer's name, trademark, or other distinctive
marking by which the organization responsible for the product
can be readily identified.
(4) The AWG size or circular mil area.
Informational Note: See Chapter 9, Table 8, Conductor
Properties, for conductor area expressed in SI units for
conductor sizes specified in A WG or circular mil area.
(5) Cable assemblies where the neutral conductor is smaller
than the ungrounded conductors shall be so marked.

How do you know all that information isn’t marked on the jacket?

How do you know all that information isn’t marked on the jacket?

I don't know that it is or isn't but based on the OP "or what don't you see?" comment, I don't see the required marking. Also, from my own personal experience local contractors can go to supply houses (or some guy's storage unit, who knows) and buy conductors that don't have the required markings. They're a lot cheaper, and the POCO uses them everywhere, so why not? 310.8, that's why. POCO doesn't have to follow NEC.

 

[Joe.B]

I suppose he's waiting for other responses before telling me if I'm right or wrong.

 

[wwhitney]

I don't see the required marking.

You can see some lettering on the conductor to the left of the purple tape near the bottom of the picture. The others are probably also labeled, but don't happen to be facing the camera.

Wayne had it right, No EGC with the FMC. We ended up pulling out all of the existing wires and pulling in new wire with an EGC. We could not pull the EGCs through the filled pipes. FMC is only rated for 20A as a replacement for the EGC.

 

[wwhitney]

No EGC with the FMC

Presumably the EMT is a proper EGC. So if that FMC is less than 6' long, then 250.102(E) would permit running a bonding jumper on the outside of the FMC, from a bonding clamp on the outside of the EMT to the generator enclosure.
