Hi all,
I have a disused "Three conductor" (neutral and two hots) 4 AWG SEU AL XHHW wire from the previous HVAC condenser unit routed towards the area where I’d like to locate the Tesla wall charging unit (about a 30ft run). The existing wire is rated at 75 amps / 90 deg C, which gives me some overhead per my understanding. It runs freely along the rim joist, and enters the 1.25 EMT conduit on the descending segment along the concrete wall.
My plan is to put this wire on a 60 amps circuit breaker in the main panel. On another end, I will terminate with a non-fusible 240v switch, which will then feed a HPWC with a short ~3 ft run of copper 6 AWG THHN (x2) / bare (x1) wires in the ¾ inch EMT conduit.
Schematic view:
No electrician would agree to this job as they'd rather run a new 4/3 Romex, but let's just say I'd like to reduce the waste and learn new skills along the way. Since this AL wire is already in the Main Cabinet, I feel that this is really within my capabilities.
Does this seem like a workable solution that will survive the inspection?
Is terminating with a switch (AL to copper) a good idea or I should rather do a subpanel?
Or shall I abandon this and go find other things to do?
