im thinking its not on a dedicated circuit. it is an unused circuit that was probably made for an extra spot to put a light or something.
my main point is , will an hpwc work on a typical 110V 20amp circuit?
Why spend $500 for a HPWC?
I park in a public garage and I use a
lockable cabinet with a plug inside to which I connect my Tesla Portable Connector.
When not in use, I keep all the cable inside the cabinet so nobody can steal the charger.
And when in use, I can still close and lock the door with the cable passing at one of the corner.
Note: I have been using 120 V with some extension cables before I was able to install a 240 V plug.
Charging was a little bit slow but if you can charge all the night you might have enough for your daily commute.
And since I mostly used my bicycle during the weekend, my car was always fully charged at the end of the weekend.
Question: Will you have to pay for the electricity.
I would recommend installing a small
Wattmetter as people would certainly curious how much electricity you used.
On this device, the
Power is the instant power delivered,
and the
Energy is the total power delivered, which can reset every month or just kept accumulating.
I would put it outside of the cabinet, and you can turn the display off or cover it to keep it discrete.
Also, not mandatory, but I would put a
rotary switch outside the cabinet, allowing to disconnect the charger.
This might be practical if you cannot access the circuit breaker
or if you cannot see the circuit breaker this would allow you to know if the plug is energized.
