Please excuse my ignorant question in advance, I did however search and came up short.
I believe house wiring requires a roughly 20% "wiggle room" in sizing circuits. IE: You cant use a 15amp circuit for a 13 or 14amp requirement. Right?
Are switches the same or are they rated for what they will truly support? My bathroom heater/light/fan (Panasonic whisperwarm) requires a dedicated 20amp circuit. The heater portion alone uses 1400watts. I'm looking at 3 in 1 switches that will safely support this unit. Broan makes a 15amp switch in which each of the 3 switches is rated for 15amps. Will the 15amp rated switch be appropriate for a 1400 watt (roughly 12.5-13 amps) heater? 13/15 is roughly 85-90%. Is this usage acceptable or do I need a 20amp switch?
Thank you in advance
