First, please be patient with me as I have several questions I’m hoping this expert community can help answer.
Some background info. I just moved into a new house. Brought my Chargepoint Home 25 (32 amp Nema plug station) from my old house hoping to simply install a Nema outlet in the garage here and operate as I have been. Have had the Chargepoint for 3+ years and it works great. Well the new home has a detached garage so getting the Nema outlet installed is a big deal, costing potentially several thousand dollars. Now on to my questions...
1. One electrician has suggested he could piggyback (my term, not his) from the existing 240 V, 30 amp circuit that supplies power to my dryer at significantly lower cost. I do realize this will charge the car slower and believe it will meet my needs. This is not code but (according to him) not unsafe as long as we don’t run the dryer and charge the car simultaneously. Any safety concerns you guys would have with this plan?
2. If I do this, I don’t think my Chargepoint will work because it’s a 32 amp device and I don’t think it is configurable to a lower power setting. If we piggyback on the 30 amp circuit, that’s 24 amps continuous. Anyone know for sure if the Chargepoint Home is or is not configurable? I believe the new Chargepoints are but mine is 3+ years old.
3. So if the Chargepoint won’t work, I may buy a new Tesla Wall Charger. I am fairly certain the Tesla units are configurable to different power levels and would work with the 30 amp circuit. Can anyone confirm this is definitely true?
4. Finally, the tax credit for purchase and installation of a new charger is available this year. I believe it’s 30% of total cost up to $1000. I took the credit back in 2016 when I installed my Chargepoint at my previous address. Any reason to think I can’t take it again this year with a new Tesla wall unit & install at a new address?
Thanks in advance for your helpful and constructive replies. This will help me make the right decision on how to proceed.
