I am installing an outlet on the front of my house to charge my Kea Niro. The current charger I am using requires a 120v 20A circuit. In the future I expect to get a charger that will require a 240v 50A circuit.
Can I run #8 wires thru the conduit for the 240v 50A circuit but cap the RED wire and just hook the BLACK to a 20A Breaker and on the other end install a 20A recepticle in a box large enough for the future bigger outlet? Then when I upgrade I can install the 50 A double breaker and the proper 50A outlet. Does all of this make sense and seem proper?
