Quick question?

Never installed anything other than SE cable to a range or air handler with electric strips, see 338.19(B)(4)(b).
The better you know the code the more $$$$$ in the pocket!!

just saying it is 10kva just doesnt do it for me. You must either take the sticker off the heat strip (preferred method, although they are difficult to take off) or mark the "Check box" as mdshunk said. Check 424.28 and 424.29 for justification. The sticker gives you the "min circuit ampacity" and "max OCPD". Now you can determine the size wire and wiring method and the OCPD to use. If you use NM then 334.80 can be a true enemy because at 57 amps you now have to use 6 SE CU and not NM.

With a 60 deg. temp. rating, #6 still has an ampacity of 55A. That is still suitable for landing on a 60 amp breaker per 240.4B, since the calculated load is only 52 amps.

Note that in my response I said, "#6 copper" and not #6 NM cable. I sorta saw what garden path we were headed down here....
