Mark Perry Electrical is a great choice for providing your electric vehicle circuit installation. EV vehicles continue to become more popular every year with many people deciding to have their own personal charging station installed within their garage, assuring that their EV always has that personal charging station. Electric Vehicle circuits are nothing out of the ordinary, it's basically a typical 240 Volt 50 Amp rated power supply similar to what you may already have for a large air conditioner or double oven. The difference is just the circuits purpose.
There is one difference to consider though and that's the duration the circuit is used which being that its used continuously for 6-10 hours, making it required to de rate the circuit breakers potential by at least 20% meaning, the 50 A circuit can safely operate on a 40 amp breaker, to aid in eliminating the possibility of overheating of the charging circuits protective breaker.Cost is primarily based on the chargers location in relationship to the main panels location.
Upgrading the main electrical panel isn't necessarily a requirement although it is helpful, an existing main panel may very well be adequate, keep in mind, available breaker space is a factor including how much existing power will be used during the charging process.
If you have a 100A x 240 Volt supply which = (24,000 watts) , that basically means you have that much power to utilize at any given time, so by managing your power consumption responsibly there really is no limit on where that power is used, as long as it's not during the same time of your AC, Spa, Double oven and so on. This is one reason aside from energy tier rates, why people charge their vehicles between late evening to early morning ( 10pm - 6am )
