Main Disconnect with no Amperage rating?

Had an inspection today, everything looked decent in the electrical panel but the main disconnect had no amperage rating on it.


Read every label on the breaker, read the panel, all I could come up with is a catalog number.

Two questions:

1. Anyone know of a way to find a breaker rating with just the catalog number?

2. Anyone know of a reason WHY the amperage rating would be missing in the first place?

Muchos Gracias.

Jeff, you might want to look at the service conductors. A #4 copper or # 2 aluminum would indicate a 100 amp rating or the meter might be a clue as well. A square meter base would be compatible with a 100 amp service. Look on the face of the meter as well. Use the meter as a last resort though because sometimes the power company uses an old meter in a new meter base when they upgrade service. Check the service conductor rating against the rating of the meter and meter base, if these match then you found the amperage service, if they dont match report the lesser rating because you dont want to report a 60 amp service as 100 amp. Thats a whole other issue there. Hope this helps.



When you’re up to your a*@# in aligators, it’s hard to remember your main objective is to drain the swamp.

Jeffery,


Write it up just the way you “see” it. Everything else could indicate it is a 100 amp service but unless you know exacty what the rating on the breaker is it is called “guessing”. Sometimes it is just what it is. If you can’t find a rating marked on the device, write that in the report. Chances are very good it is a very old breaker. I have run across a few myself and I just write what I see and don’t try to figure out what someone else did some time in the past.

Did you google the number? Maybe without prefixes and suffixes.


You can also search the mfg web site.


I have tracked down lots of things that way.
