220 wall switch

I am installing a 220 20 amp line (12 gauge)to an air handler in my attic. I am told code requires a wall switch near the unit to turn off the power. Would a 2 pole 15 amp switch suffice for this, or do I need a special 20amp type switch?

When you remove the acess panel that covers the wiring compartment where the "external" wiring connects to the "internal" wiring, you will find a punching in the metal surface of the AHU that when removed gives a circular opening , 1/2" diameter,for a cable-connector. Locate the switch-box there- it's the most convienient and practical location for those who will service the AHU.

It's very improbable that a D-P switch rated at 20 amps is required-- check the name-pale for full-load motor current.

If you'r the type of person who is meticulous about you'r home's "systems", please allow me to cite a relevant Code Article (210.63)-----" A 120 volt receptacle outlet shall be installed for the servicing of (HVAC) and refrigeration equiptments"

Good Luck & Enjoy the Experience!!!!!!!!!!
