i assume that SSR you list is a 25amp based on the part #? if you can, get a higher rated SSR, it'll get less hot as it isn't as close to its limit.
I was not planning on using a selector switch... I was just hoping by using two elements it would use less amps.
So basically I need something under 80% of 20Amps. It does not matter how many elements.
Will a single 3500W / 240 = 14.6 amps element heat up and maintain my HLT to 175 degrees?
And is the bigger the SSR the better? say 40A?
