Can I put a 50 amp EV charger on a 125 amp panel?
Installing a 50-amp EV charger breaker is restricted when a main panel shows only 125 amps of capacity. Additionally, configuring wiring such as running Romex down inside a pipe instead of next to it creates further physical installation complications.
What people tried
Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.
- 1Running the charger off a sub panel
- 2Installing tandem or quad style breakers to make space
- 3Charging at night when the AC is less likely to be running
- 4Install a junction box where existing metal-clad cable and metal conduit meet to transition and run appropriate individual wires.
