Phase 1: The first step in wiring a three phase heater is to identify the three main power lines. These are typically labeled L1, L2, and L3. These are typically labeled L1, L2, and L3. Make sure to turn off the power supply before proceeding with the wiring to avoid any potential electrical hazards.. 9 element heaters — 45-54 kw — 208, 240, 480 volt — 3 phase standard hi-power® wiring diagram immersion thermostat/magnetic contactor models 6 element heaters — 27-36 kw — 208, 240, 480 volt — 3 phase cp-5m-04/09-printed in u.s.a. r l1 l2 l3 bk bk bk bl bl bl l2 - black l1 - red 3 phase r - red l3 - blue bl - blue bk - black color code
