This 2AWG 35mm2 cable is rated at 188A continuous. The Weld Flex rated at 220A is a bit thicker and did not feel as flexible in cold weather, decided to go with first cable.
Each toriod will only be required to handle around 3kw continuous, and that would be for around 1 hour a day worst case, so a total of 6kW continuous for 1 hour, the current single 3 stack inverter can do that, and start huge Induction motor loads.
A lot of 2AWG cable from typical electronic and electrical outlets appears to have a very thick but still flexible covering, however some of it is only rated to 150A with no indication of duty cycle.
That 150A tinned copper cable (I know tinned is dearer) is currently almost twice the price that I payed for the 188A cable, and 15 months ago the 150A cable was 30% cheaper, even then it was still a lot dearer than this higher rated.
2 B&S (35mm2) 188 amp Copper Cable Single Core Australian Made Nom Area: 32.07mm2 Rated to 188 amps Continuous Use Applications: Battery and Starter Cable, Inverter, Dc-Dc Systems Conductor: OXYGEN FREE Plain Copper Wire to AS/NZS 1125 Insulation: V90 PVC to AS/NZS 3808 Australian Made UV Stable 5V90 PVC Cable
As with the first 3 stack toriod, a heat gun on low heat is used to warm the cable on each pass through the toroid, especially each bend, it sure makes it easy to pull straight and get tight curves around the toroids, and shortly after removing heat, the cable holds shape and does not try to unravel. I will also seal the crimp connectors when final lenght has been determined.
