Technical Notes

The furnaces covered by this manual have electronically controlled power limits. Do not attempt to
calculate the Amps from the Wattage. High break capacity fuses should be used. Avoid fast-blow
fuses and magnetic trip circuit breakers - consult Carbolite if in doubt.

Two-phase models use two phases out of a 3-phase+neutral supply. One phase is unused. The
neutral current is equal to the current in one of the used phases.
