Booster Heater Element Field Conversion from Single to Three Phase Operation (continued)

ATTENTION ELECTRICIAN:

The Main Terminal Block (MTB) is a 4-wire connection block which includes a current-carrying neutral. The block can be connected for 3PH or 1PH depending on how the booster heater is wired ( see the previous page).
