I think Tesla screwed up my panel labeling. Need to know what the experts think.
I have a 200 amp disconnect switch outside between the meter and TEG, I think should be marked “Emergency Disconnect, Not Service equipment”.
Then I have a generation panel outside that goes to the TEG combining battery storage and Solar, I think that should be marked “Emergency Disconnect, Service Disconnect”, or perhaps “Not Service Equipment”. Kind of torn on this one, there is also a 400 amp battery panel inside the garage that lands to this panel. What should the breaker inside the TEG be labeled?
Panels in garage should be labeled service equipment. Do the emergency panels need to be labeled? 1 of 3, 2 of 3 and 3 of 3.
I really think the generation panel main breaker is an emergency disconnect or the house will still have power! Code is not real clear about battery storage yet.
My install thread: Installation is starting - 8 PW and 12 solar panels
2020 Code Language:
N 230.85 Emergency Disconnects.
For one- and two-family dwelling units, all service conductors shall terminate in disconnecting means having a short-circuit current rating equal to or greater than the available fault current, installed in a readily accessible outdoor location. If more than one disconnect is provided, they shall be grouped. Each disconnect shall be one of the following:
(1) Service disconnects marked as follows:
EMERGENCY DISCONNECT,
SERVICE DISCONNECT
(2) Meter disconnects installed per 230.82(3) and marked as follows:
EMERGENCY DISCONNECT,
METER DISCONNECT, NOT SERVICE EQUIPMENT
(3) Other listed disconnect switches or circuit breakers on the supply side of each service disconnect that are suitable for use as service equipment and marked as follows:
