The Heater current charts may assist in selecting the proper contactor arrangement. If you are unsure of the correct sizing, we can assist in the selection.
Note on incoming power wiring:
The main incoming power wire requirements are sized based on the total heater nameplate kW and voltage. Calculate the actual load on the heater contactor control panel (the total kW of all the heaters connected to it) or use the nameplate rating in determining the wire size required.
Calculate the amperage as follows:
Single Phase Amperage = Total kW x 1000
Three Phase Amperage = Total kW x 1000
Voltage x 1.732
The field supplied branch circuit disconnect switch and the branch circuit protective devices (fusing or circuit breaker) should be sized to carry at least 100% of the current calculated above.
