![]() ![]() If you install a 14-50 with 6 gauge copper wire the cable will have 2 hot conductors (red and black) a neutral conductor (white) and a ground conductor (bare). If you don't have space in the panel costs will rise from there. ![]() A nema plug with the extra neutral would cost another $50 of wire (for my 50' run) plus maybe another $20 for the actual outlet and a nice cover, plus maybe $75-100 for a 50A dual pole CAFCI/GFCI breaker (the tesla charger has GFCI built in and requires a simple $10 60A breaker).įor labor, it was about a 3 hour job for me since I don't bend conduit every day, a pro could probably do it in 2 hours, or if its right under your panel in well under an hour (at $50-$100 per hour plus whatever the 'trip charge' is). Including a discreet ground (10GA) and a bunch of 3/4" EMT conduit the total materials cost was around $130 (about $100 was the 6ga wire). ![]() To give an idea on parts costs: I installed my gen3 wall charger ($500) at the end of about 50' of conduit (one side of garage to the other). Both need 6GA copper to a 50A or 60A breaker and the plug solution also needs a GFCI (new for NEC 2020, even dryers get GFCI's now). Installing the 14-50 with 60A (usually 6AWG) wire will future proof in case you want to install the wall connector later.Īs mentioned elsewhere, the 14-50 is a little more costly/complex than the official charger in terms of installation. The only change the electrician would have to do is take out the 50A breaker and put in a 60A one which is easy and cheap.įor the majority of people's installs the mobile charger which charges it 32 amps, usually on a 50 amp breaker with a 14-50 outlet and getting 30mi/hr of charge is plenty. If you wanted to be more future proof you could ask them to install 60A rated wire that way later on you could remove the 14-50 outlet and hardwire the wire into a wall connector. Since most people want 40A for the mobile connector, and there isn't a standard 40 amp outlet, they install the standard 14-50 outlet with 50A wire and breaker. Because continuos draw on the wire requires de-rateing by 20% for safety, when doing continuos 32A or 48A, the wire and breaker needs to be rated for 40A or 60A, respectively. Most people even with the 48A capable cars use the mobile connector because 32A is fast enough for most home charging. 32A will get you ~30mi/hr of charge and 48A is ~44mi/hr. To take advantage of that though you have to use the wall connector since if you use the mobile connector it limits you to 32A. The other larger battery model 3's, Y's, S's, and X's internal charger is upgraded to 11.5kW / 48A. If you are using the mobile connector, your charge limit is 32A / 7.6kW which matches the 3 SR+ and (asumidly, not confirmed yet) Y SR maximum ac charging capability. ![]()
