Why Installing a 240 Volt EV Charger isn’t that Easy..🫡 #electriciandad #hendythesparky

What happens here

The electrician proceeds to install a two-pole slimline breaker (40 amp) into the electrical panel. He stresses the critical importance of using a two-pole breaker for 240V circuits, as it's necessary to tap into both sides of the busbar for the correct voltage supply. He advises against installing slimline breakers on a single pole. He then demonstrates his preferred method: first, 'dressing' the wires to organize them, then aligning the breaker's groove with the corresponding slot on the busbar. He securely pushes the breaker into place until it locks, noting that this method is often easier with thicker gauge wires compared to connecting wires to the breaker before installation.

Goal: Securely install the two-pole breaker into the electrical panel and connect the charger's wires.

Tools and materials

  • Screwdriver — To tighten the electrical conductors into the breaker terminals
  • Two-Pole Slimline Breaker — To provide overcurrent protection and a means to disconnect power for the 240V EV charger circuit

What they say

Hide

these slim line breakers. So, you want to make sure you don't put these on a single pole, right? Why? Because you need to catch 240 volt power. You need to catch both sides of the bus. You think putting the wire in first with the breaker is better? I never normally do that. Everyone's a little bit different. You can do that. Okay. On this skinnier wire, it's easier to do. On thicker wire, it's harder to do cuz you can't really maneuver. What I'll do is I'll just kind of dress my wire. Now, I've got that groove here. What I'm going to do is put that groove in first. It's going to lock in. Yeah. Then I can push it in. And now I'm ready to fire it up. Nice. Going to tuck our wires in. Nice. Nice. Out of the way. And uh I think he's ready to turn it on, right? Yeah.
