Can I wire a transformer to an outlet cord rather than hard wiring into hvac system. Adding a GPS to air handler and it requires its own transforme. Any suggestions??
No problem, only question is how good you want it to look
Doorbell transformer, made to order has connector to go into an electrical junction box.
Head to home depot, or lowes - find an electrical box you like, plastic, weatherproof, metal and a cover plate for it
Add a doorbell transformer
A small pack of romex connectors (nmb might be the name on them)
a couple of wire nuts, yellow
A round extension cord that appeals to you.
Cut off the female end of the cord, and assemble as it appeals
