Hello,



Can someone please tell me what AWG copper line is required to service a 68.5
amp 240vac tankless water heater? The manufacturer recommends an 80 amp
breaker.



Thank you

Bill


there is all kinds of type wire to choose from as distance of run and as in
conduit or not and you can run it in # 6 to a # 2 by just what type wire it is
and the metal the wire is made out of.

So if run in Copper wire run # 2 and you can't go wrong. the wire can be smaller
if you tell the conditions like length of run , type of wire you have to use ,
and in conduit or out.
