Recently had the electrical panel upgraded and relocated. The electrician showed me the main wires coming from the street (in to the meter) and indicated they were 1/0 aluminum. The breaker panel had a 125 A main breaker, and he put in a 150 A main breaker on the new panel (the new panel is a 200 A panel). He replaced the wires from the meter to the panel with new copper (forget the gauge). From what I've seen around here on DIY.SE, though, 1/0 Al is sufficient for only 125 A, not 150. Should I be worried?
I'm in the Houston, Texas metro area.
We never tripped the 125 A breaker, but did add a 50 A 240 V receptacle for EV charging. No EV yet, and its breaker is off, so we're not drawing any more current than we used to. I'm not really worried about an immediate problem, only once we get the EV.
