Lawrence, Even though the (cold-exposed) breaker might not trip, please remember the purpose of the breaker is to protect the *wire* after the breaker from overload. If that wire run through insulated walls, it might overheat and get damaged, even though the breaker does not trip, so please refrain from overloading a breaker just because you can. I remember reading the report from a fire inspector who was called to a home that was remodeled and existing walls were insulated and new sheetrock installed and painted in winter and so in order to let it dry properly they used two small electric space heaters to warm up the remodeled room, but the breaker kept popping so they replaced the 15A breaker with a 20A one without checking wire gauge. The next night the room caught on fire because the undersized wiring in the newly insulated wall was overheating from the combination of the increased breaker rating allowing more current than the wire size was rated for and the new insulation preventing the hot spot to get adequate air flow cooling... If you can, please check with LeafSpy how much the car is actually drawing from the 240V EVSE and make sure to either modify the EVSE or the service to keep the continuous draw at 80% of the rating of the circuit.

I have been charging the 30kw Leaf for hours now and still not tripped the breaker here in Modesto. However the temperature is near freezing. I'll check again soon and report back. Temperature does make a difference. A frozen 20 amp service will suffice for a while for a 30 amp EVSE. Lawrence Rhodes -------------- next part -------------- An HTML attachment was scrubbed...
