Hi,
I'm wiring four new electric baseboards in my basement.
All four are 220Volt units: 500W, 500W, 1000W, 1500W, for a total of 3500W. From the main panel to the farthest unit is less than 100ft.
If I understood the rules, putting all of this on one circuit will require a 20Amp breaker (1.25*3500W/220V), and the wire can be #12AWG.
Did I get that right, and am I missing any other design factor?

Many thanks, especially if you can reference the NEC so I know I'm doing it right.

OK first things first, heaters are rated at 240v not 220 so your total
load is 14.6a.

OK lets look at the code (Fixed electric space heating art 424)

Why? Why not just do the sums and work out what's actually needed instead of believing some paper pushing ****wit?
