Can I land multiple wires on one terminal on UL1077 and UL489 MCBs?
For the UL1077, Yes, multi-point interconnection is allowed per UL508A. Per the below table, the MCB would be rated at 10kAIC. For UL489, additional test needs to be performed and as of right now, multiple wires on UL489 MCB is not allowed.
