Hey guys so I posted about this heater we installed a couple weeks ago I need a couple more opinions on the matter but basically I have a 5000 watt heater. 2 pole 30amp breaker 10/2 romex from panel to switch and 10/3 up to the heater. Per the manufacturers instructions they recommend tapping down to #12 once you hit the switch. I was able to do so for the hot side or input side of switch but Im running out of room to make anymore joints to tap down the 2 switch legs which are #10. The switch is a Leviton 20amp stack switch so I called leviton after I left the job and they’re saying the switch is only rated for #14-#12 I got a good wrap on the switch and it’s definitely not loose but I’m wondering if I should go back and try and tap down the 2 switch legs to #12
