Cal. Code Regs. Tit. 8, § 2730 - Switches in Parallel (Multiple)
When the load of an existing service entrance switch increases beyond its continuous current rating or continuity of service requires, a second service entrance switch of identical rating shall be permitted to be connected in parallel with it, provided:
EXCEPTION: Both switches need not have a common tripping arrangement if continuity of service requires that both switches not be tripped together, under fault conditions, and a suitable relay protection scheme is employed to separate faulted portions from the system.
