What happens here

A new 40 amp circuit breaker is installed into the existing electrical panel. Following this, 8 gauge THHN wires are pulled through the newly installed 3/4 inch EMT conduit. The wiring consists of two 'hot' wires (typically red and black) and one ground wire (green or bare copper), which are necessary for powering a 240-volt continuous load EV charger.

Goal: Provide power to the EV charger from the main electrical panel.

Tools and materials

  • 40 amp Circuit Breaker — Protecting the EV charger circuit from overcurrents
  • 8 Gauge THHN Wires — Conducting 240-volt electricity from the panel to the EV charger (two hot, one ground)
  • Fish tape — Pulling wires efficiently through the installed EMT conduit
  • Headlamp Klein Tools — Illuminating the work area inside the electrical panel
  • Lineman's pliers — Cutting and twisting wires for secure connections
  • Screwdriver set — Connecting wires to the circuit breaker and securing panel components
  • Wire stripper — Stripping insulation from the ends of the wires

cutting the [music] sheetrock with the multi-tool. Here's where the EV charger is going. There's no other way to do it, guys. You have to cut the wall. We then start installing our 3/4in EMT [music] conduit for the charger. We installed a 40 amp circuit breaker and ran 8 gauge [music] thhn wires, two hot wires, and one ground wire. Cuz this is a 32 amp continuous load [music] EV charger. I start snaking my wires and strip the jackets. Only need about 1 in of copper. Don't have to go crazy. The [music] Tesla charger is 240 volts. I then
