1. The 20kW heater model (6HK46502025) come with service disconnects standard.
2. MOP = Maximum Overcurrent Protection device; must be HACR type circuit breaker or time delay fuse. The 1st circuit includes blower motor amps.
Refer to the latest edition of the National Electric Code or in Canada the Canadian electrical Code and local codes to determine correct wire sizing.
kW & MBH CONVERSIONS - FOR TOTAL POWER INPUT REQUIREMENT
For a power distribution voltage that is different than the provided nominal voltage, multiply the kW and MBH data from the table by the conversion
factor in the following table.
