Do I recommend to upgrade panel?

[Mark P]

Question: 2/0 AWG going to a 200 amp main breaker inside a box rated for 100 amps. Is this a safety concern? What recommendation do I make?

Thanks in advance.

Assuming that's 2/0 copper cable and not 2/0 aluminum, and you've carefully studied the label and are correct, the panel is not being used according to it's listing and labeling:

You can either:

a. Have the main breaker replaced with a 100 amp breaker (if that's possible with 2/0 cable)

or

b. Have the panel upgraded to a 200 amp panel.

OT - OF!!!

Thanks. Here is a picture of the label in the panel, best I can read is 100 AMPS.

I think you have it right Mark. That's a 100 amp panel. It's like Mike says, they need to make the main and panel ratings agree one way or the other. They also can't clip strands out of the 2/0 to make it fit in a 100 amp breaker, so if they go that way the wire will have to be replaced too. No way it'll fit into the lugs of a 100 amp breaker.

Yep,

It's clearly printed there on the label - Maximum wire size No. 1 AWG so the cable has to go too.
