Does a CT cabinet require work space compliance?

[steve66]

What, inside the CT cabinet is exposed electrical components?

The code paragraph i'm looking at doesn't say there has to be "electrical components". It just says equipment likely to require examination, adjustment, servicing, or maintenance....."

At the very least a CT cabinet will contain the terminations for the line and load conductors, and some type of bussing from in to out.

The meter and the CT cabinet are "under the exclusive control of the utility", and even where physically on the load side of the service point, are outside the scope of the NEC per 90.2

I feel like a lot of inspectors are going to make sure the service complies anyway. From my experience, the utilities (at least the ones around here) do not inspect any of the electrical installation. They just look for the approval from the local AHJ or inspector, and if that's present, they will connect.

Around here, where few cities have local inspection, the utility looks for compliance to their standards before they will connect a service. In my small town, one that does have inspection, they look for our sticker.

They are as soon as the utility puts their seal or lock on them.

Nope. Still owned by someone else.

owership has nothing to do with the code rule

Says who? Where is that defined? Regardless, I'd maintain that just because a utility puts a seal on something doesn't put it under their exclusive control.

The bottom line is if it's going to be inspected by an AHJ it'd be prudent to clear it with that AHJ before you build it if it's going to be hard to change afterward.

We only have a final inspection here . So I am unable to ask inspector earlier than on final.
I can ask poco inspector on preliminary meeting.

Here, Poco pulls meters, but as electrician I can cut seal and pull meter in emergency if I call and get permission. I would say that’s exclusive control of utility. Plus their AMR system reports if meter looses power. No provision for cutting lock and seal on CT can.

Ownership and control are distinct ideas. What changes would the owner be allowed to unilaterally make to the sealed CT enclosure? If none, then it is under the exclusive control of the utility.

We are not going to agree on the ownership issue.

It's not 'exclusive' if the owner has the right to contract with someone to remove, move, or upgrade the equipment and the utility is bound by regulation to abide by any such request that meets its published rules. Also it may be legal for an EC to break the utility's seals in an emergency situation, in which case it's particularly apt for the NEC's scope to apply.

I know it was mentioned but I’m sure the utility has a service guide with clearance requirements very similar to NEC. I really think this is a non issue.

This post has gone on long enough. I agree with Don
