If a fancoil is 208 1ph with a little DC motor at 1.3FLA and the max fusible for the unit is 15amps. Can I use a 2p toggle switch with lockable means by itself if its feed from a HACR breaker or would I still need a in-line fuse to the switch. Instead of a bulky 30amp disc. with 15amp fuses. I have 20+ units.
