AF labels on load bank or camlock?

[lielec11]

I'm curious the communities opinion on putting arc flash labels on items that are normally off and only used in a generator testing environment. I'm talking about things like a load bank or a camlock box that may be used to connected to a load bank or a roll-up generator. IMO we do not typically include them in our study as they don't carry short circuit ratings, have devices to coordinate with, nor are they typically operated on live. But we have a client who is basically going item by item on a one-line claiming they are part of the scope. I want to appease them but I'm not even sure if you can quantify any results. Thoughts?

When I did studies, I would include generator tap boxes. However what are you going to use as the source of the fault current? Load banks and generator connections are usually isolated from the utility service by some type of transfer mechanism. Do they have a typical generator?

Well the load banks are connected to the gen bus by a breaker. Along with another breaker that feeds an EMDP switchboard. So technically the fault current would be provided by the genset. Have you actually seen AF stickers on a load bank in the field? Or printed them before?

Yes. Not often, but I have printed and installed them.
