An update on installing a Level 2 car charger … I've made up my mind about what I'll do.\n\nFirst of all, a car charger requires a 40A 240V circuit. I'll need about 100 feet of Romex to run from my main electrical panel in the basement to the garage. Some of that must go underground. Romex is now expensive, but the outdoor\/underground grade hardly costs any more. (Thank goodness for small things.)\nI'm going ahead with a new, larger, circuit breaker panel. There was really no choice about that. My old 30 slot panel is full, and if I want to add an EV charger circuit, I need a larger panel. The only choice was in how big a panel, and of what quality\/price?\nMy detached & unheated garage can hold 2 cars. At present, I'll only have one charger for one EV. But why not equip the garage for the future possibility of two chargers? For one charger only, I could run Romex straight into the garage and terminate it with a standard 4 prong 240V plug (NEMA 14-50). Instead, I will have a circuit breaker sub-panel inside the garage with two circuit breakers for two 40A car chargers. The additional cost for Romex capable of that extra current was hardly much more – but the sub-panel is not cheap. For now, I'll have one car charger. In the future, I can easily add a second charger without any additional cost, other than the cost of the charger itself.\nThe work is estimated to take 3 days. The electrician & 2 assistants will start next Monday, when they'll replace the main panel. My electric power will be off that day. The next day or two, they'll install the line to the garage and the sub-panel switch box. As usual, the 3-day estimate is probably longer than needed. It may get it done in less time, 2 or 2½ days.\nThe car charger I ordered hasn't shipped yet. When it arrives, I can install it on a stud nearby the sub-panel & plug it in myself.\n\nI won't discuss the price for all this. Suffice to say, it's not cheap. But neither is an EV. I don't want to generate posts informing me I could do this at a lower price – that's not my reason for this thread.\n\nHaving a Level 2 car charger must be thought of as part of the price of getting an EV. The cost of a Level 2 charger, plus the cost of powering it with a 40A 240V line is not small. But that cost can vary by a lot, depending on your particular circumstances. You must learn your own situation:\n\nDoes your present circuit breaker panel have enough capacity for a car charger?\nIf not, it must be replaced – or – it might be modified by adding a sub-panel.\nAnd finally, do you want to have only one car charger, or wire things for two chargers?\n\nOf course, I'm thinking only what it takes for a single family house, or town house, with it's own garage or off-street parking. I'm not tackling what it might take for any other circumstances.
