    Ghetto NEMA 6-20 Charging with two 120v 20a outlets

    Home single phase isnt rocket science, thats why most state building codes allow homeowners to do their own electrical besides panel install. Once you understand how the 2 hots, N and G interact, you can pull all the power you want all over the house. I think its great he shared. It motivated me...

    Ghetto NEMA 6-20 Charging with two 120v 20a outlets

    You cant just replace a single breaker with a tandem. They will both pull from the same leg. You need to replace two single breakers with a quad. I did this in my shop. The quad pulls from 2 legs and has a single tied 220 breaker in the #2 and 3 spot. All the counter arguments against this...

    Ghetto NEMA 6-20 Charging with two 120v 20a outlets

    Ok. So i built this in a few hours. The cord was the most expensive part. You have to push the button to close and latch the 2 pole contactor. There is a slight voltage present on the unplugged cord if the other is in because I put the voltage meter on the line side. This was so i have an...

    Ghetto NEMA 6-20 Charging with two 120v 20a outlets

    The breaker box would always be better. I pulled a 14,50 in my garage. The problem im running in to is visiting friends. Charging on a 5-15 is useless. Even staying the night adds basically nothing. I thought about carring a 30a pig tail to just open their breaker boxes and leave it open when im...

    Ghetto NEMA 6-20 Charging with two 120v 20a outlets

    what do you think is in the 220 combiner? Its a contractor wired to the two legs. Without 220 from opposing legs, the contactor is open. You also can't get any voltage with one plug in anyways, the leg just ends at one side of the plug. Its no different than a 220v extension cable with a missing...

    Ghetto NEMA 6-20 Charging with two 120v 20a outlets

    I wired most of the high load add on circuits in my house and specialize in controls. I dont get why everyone is terrified of messing with these cars and electricity. Hell working on anything can be dangerous. Almost lost a finger in a serpentine belt when i was younger and dumber while timing...

    Ghetto NEMA 6-20 Charging with two 120v 20a outlets

    I like the OPs post. Id build one for a friend that understands what outlets can be used. Id assume this would be a solution for a renter. Its so easy to pick apart other ppls ideas, but everyone's situation is different. Id also use something like this while traveling. Maybe just carry a cheap...
