Items Needed
•
Couplers: A typical multiple unit will have 4 wires (3 phase + neutral). Some will
have 2 wires (1 phase + neutral) or 3 wires (2 phase + neutral). The sizes will
typically range from 2/0 to 600 MCM.. The most common sizes are 250 MCM
and 500 MCM. A qualified electrician can determine both the number of phases
and size of cabling by inspecting the electrical system. One coupler must be
installed on each phase, but NOT the neutral. In each case, be sure to
choose the proper number and size of couplers.
