I bought an electric vehicle awhile ago and had a EVSE (power box to recharge it - Electric Vehicle Support Equipment) installed which has been working great. The box just has simple status LEDs on it, and I was curious about the line voltage and current that was being drawn, so I just got delivery of a panel mount V and A meter. As a sanity check, since it came with absolutely no instructions, I wanted to double-check how to run the current carrying lead through the toroid. I'm pretty sure that I'd only run either L1 or L2 through the coil (toroid), and not both. Is this correct? Do I need to worry about trying to get it to run nice and straight through the coil, or doesn't it really mater? What about the other power lead, do I need to run it as far away as possible in the box, or doesn't it really matter? The ID of the toroid is about 3/4", and we're dealing with 8g power wire, so there's a lot of room for moving it around.
At least on the back of the thing they did label the inputs. The specs on-line indicate it should handle the voltage and current associated with the EVSE with a fair margin.
