What happens here

The existing utility wires are extended to ensure they reach the new meter socket comfortably. This involves butt-splicing new sections of wire to the existing ones. Additionally, an expansion coupling is installed in the PVC conduit leading to the meter socket. This coupling is crucial for allowing the conduit to expand and contract with temperature changes, preventing stress on the electrical system and maintaining integrity.

Goal: Ensure adequate wire length and thermal expansion protection for the conduit.

we're putting in a new 320 amp meter socket. This is the old socket. You can see the hot bar was busted. [music] So, we're installing right now a 320 amp new meter socket. I'm holding the electric meter right now by the utility >> [music] >> and we extended the wires because the previous PVC conduit didn't have an expansion coupling. So, we installed an expansion coupling and we butt spliced the utility wires to make them longer. Make sure to check your state if you can do this. In New Jersey, you're allowed. All right, new meter socket complete. Now, we're on to the second job. So, the same customer requested that he wanted a
