Three terminals split the total rated wattage into two equal circuits. By using a three-heat switch 1/4,
1/2 or full wattage may be obtained. Use the two equal circuits in parallel to obtain full wattage.

/* Designate voltage, i.e.; insert 120 for 120 Vac or 240 for Vac.
Those model numbers containing /120 or /240 are only availiable in that voltage.
† To determine maximum allowable watt density, see Figures C-8 or C-9.
