Bonding neutral and ground at service end box in NYC

[electrofelon]

No, a main bonding jumper by definition is in a service disconnect enclosure.

I wanted to say that, but it's actually not in the definition (unless it's changed after the 2017). The definition says "....at the service", and the definition of "service" isn't restrictive to just the service disconnect, as I read it.

Okay it's not in the definition, but it *is* in 250.24(B).

Right and I thought I mentioned that and 250.28 but I can't for the life of me find it, maybe I'm on crack . In any case, can you think of any reason they couldn't change the definition of MBJ to ".... In the service disconnect(s)" ?

No.

Are you allowed to bond ground and neutral at the service end box instead of service switches? Not sure if this is ok in NYC

A MBJ would NEVER go in an endbox regardless of utility requirements.

I can't think of a time where Con-Ed sealed their service end box.

I am talking about a Con ED service end box in a typical NYC basement, these boxes are installed before the meter to separate the service lateral from the service entrance conductors, are we talking about the same box? They are required to be sealed, because they are before the meter.

In this photo above the meters is the con-ed box, note the seals on the meter and the end box:

I'm talking about EO-9072-B or EO-9073-B boxes

Yeah I would be surprised if Con ed didn't seal the end box, unless there was metering before it.
