Add 240 breaker. Branch breaker 100 amp. Any 2 pole 240v breaker needs to sit in 2 spaces so something special will have to be done. Please help me understand if i will need a service change like 2500 or just able to add a 240v circuit breaker in the panel that would be much less expensive. Before installing a 240 volt receptacle shut off the main breaker.

The second is that 240 volt circuits carry high amp current. Two characteristics of 240 volt wiring are important when you re installing a new circuit breaker. The first is that 240 volt wiring requires two hot wires not just one as 120 volt circuits do. The result is the maximum current in amperes amps for the circuit.

Route the cabling from the 240v circuit into the breaker box. Secure the cable in the clamp. Attach the white wire to the neutral bus bar and the ground wire to the grounding bar. A subpanel is a mini electrical panel that is fed from the main panel to create spaces for more circuits.

A 120 volt circuit has only one hot wire connected to the breaker plus a neutral wire connected to the neutral bus bar in the service panel. Once you ve confirmed the power is off fish wires from the receptacle location to the panel. Using a duplex breaker for two 120v circuits to free up a space. Adding a new electrical circuit to your home also requires that you add a new circuit breaker to the electrical service panel.

Meter socket rated 200 amp continuous. That means you need heavy gauge wire to prevent overheating. Step 4 cut off the outer sheath of your 4 strand cable to reveal its inner wires. Punch out one of the knock outs on the top of the box and install a cable clamp threading the cable through the clamp and into the box.

A 3 wire 240 volt circuit has two hot wires each supplying 120 volts for a total of 240 and an equipment ground wire. You can check that the power is off by using a voltage tester and testing both plugs. Divide the total number of watts by 120 or 240 for a 240 volt circuit.
