ECN Forum Forums General Topics of the Trade General Discussion Area new breaker box blew out my a/c - who pays?

Somewhere close to the A/C unit should be a disconnect.

It is usually not part of the electrician's job, as a part of the panel change out, to check what size fuses are in it, or determine the proper size fuses.

The new breaker box has nothing to do with the A/C condenser failure.
