I can't be the first person that needs to distribute 120vac (or and voltage) via a multi-Relay board. Is there some kind of Buss available for the common side or do I have to solder 8-pieces of wire to a longer piece of wire that then connects to the hot side of the Mains for an 8 x Relay board?
The board screw-connectors are not big enough for two pieces of #16 wire which is the barest minimum wire-size for 120/10-A. So, for now I am making something looking like suckling piglets on a mother-wire.
Begs the question for the makers of the relay boards. "Why have 10-A relays if I can't get two 10-A rated wires into a single screw terminal?
