When installing a 100A sub-panel with larger wire (3-3-3-5 copper SER), is there a specific size of wire clamp I need for this? Do I use the same type of wire clamp as I would for NM cable, just larger (like the type that go into the knockout with a nut and have some screws to tighten the cable)? Is there a specific size of clamp I need?
I think the codes I’ve seen (which I haven’t search through exhaustively) just say the wires need to be secured and follow the manufacturer guidelines or something. Would appreciate any specific parts I should buy.
