Frequently Asked Questions about MRCOOL 7.5 KW Signature Air Handler Heat Strip with Circuit Breaker, MHK07H

Most Frequently Asked Questions

A 7.5 kW heat strip operating at 240 volts typically requires a 40-amp double-pole circuit breaker, but you should always confirm the exact breaker size in the manufacturer's specifications and comply with local electrical codes.
The breaker size for a heat pump air handler depends on the unit’s electrical specifications, but it typically requires a 15- to 30-amp double-pole breaker on a 240V circuit; always consult the manufacturer’s installation manual and follow local electrical codes for the exact breaker size needed.
Most air handlers do not have a built-in circuit breaker; instead, they require a dedicated circuit breaker installed in your home’s electrical panel, sized according to the manufacturer’s specifications and local electrical codes.

Other Questions

Heat strips on an air handler are electric resistance heating elements installed inside the unit to provide supplemental or backup heat, especially when the heat pump alone cannot maintain the desired indoor temperature in colder weather.
Yes, heat strips use a lot of electricity because they rely on electric resistance heating, which is less efficient than heat pumps, typically consuming significant power (e.g., a 10 kW heat strip uses about 10,000 watts per hour).
