Hey All
I have 70feet of "6 AWG, Type MTW/UL1283 Wire, 266 Strand, Temp 105C"wire between PV array and Controller. The wire is in EMT conduit.Today - at 38a the wire is running40C/105F- e.g.'warm to the touch' and its not a problem... BUT...
How hot is too hot?
I asked because Iadded panels to max out my Midnite Classic 150s and as summer approaches they will reach 45+ amps and thehe wire will get hotter. Here's the specs:
The Midnite offers current limiting, so I can control this but I'm thinking that it will become a question of how hot is too hot (unless I run 4awg wire - a big pain!!)
