The Alpine branded heater coils can be manufactured either by Goodman or by Warren. They are designed to install in and work perfectly with the Goodman air handlers they are accessorized to. The amperage requirements for any heater coil can vary depending on what piece of equipment it is installed in so please review the documentation section for specific details.  

This 240 volt heater coil can be added to a Goodman air handler to provide winter-time heating capabilities. 

Produces 16,200 BTUs of heat.

Controlled by sequencers for optimum temperature balance. Completely assembled and tested. Built-in overcurrent protection on all units as indicated in electrical data chart (see spec sheet). Multiple branch circuit capability. High temperature limit controls for safe operation. Plug-in wiring harness for easy installation into air handlers. Rust-resistant nickel chromium heat elements.

If you are installing a heater coil in an air handler, line voltage is to be connected directly to the heater coil which will operate both the heater coil and air handler. A separate circuit for the air handler is not needed. 

Depending on the heater coil size being installed, one or two circuits to the heater coil will be necessary (see "Documents" below for quantity and amperage of circuits required for this heater coil.) At your home's circuit panel, individual 220 volt double-pole circuit breakers are required for each circuit.
