How do you wire a 120v sub panel?
Quote from Youtube video: And a white neutral wire. The ground wire goes over to a dedicated ground bar here in the corner. The neutral goes to our neutral bus right here. And then our hot wire goes to one of the two spots.
What wire goes from meter to panel?
SE-U is most commonly used for service entrance applications, to connect the meter socket to the main breaker panel. It is also commonly used for overhead service drop applications, to connect the overhead service cable to the meter socket.

Does a subpanel need to be grounded to the main panel?
Most panels come with a bar joining the two, which is easily removed. Code requires subpanels to have a ground connection that’s independent of the main panel’s.
How do you wire a 120V breaker box?
For 120V single phase circuits, the single pole circuit breaker is connected to the one hot busbar (either Hot 1 or Hot 2) and Neutral.
Inside Main Breaker Box
- Hot 1 or Line 1 = Black Color.
- Hot 2 or Line 2 = Red Color (for illustration purpose only)
- Neutral = White Color.

It takes special training and equipment to pull a meter. The power company will know within minutes of you pulling the smart meter if it is monitored and read remotely. They will know if you tampered with the lock and removed the meter.
Why do you have to bond the neutral and the ground wire in the main panel?
With ground and neutral bonded, current can travel on both ground and neutral back to the main panel. If the load becomes unbalanced and ground and neutral are bonded, the current will flow through anything bonded to the sub-panel (enclosure, ground wire, piping, etc.) and back to the main panel.
Why do you not bond a sub panel?
So, why do you separate the ground and neutral in a subpanel? Because when we bond them together, it gives your neutral wire (the one carrying electrical currents BACK to the source) multiple pathways. That’s how the chassis of some equipment will become energized.
How far can sub panel be from main panel?
You must provide from 3 to 4 feet of clearance on all sides of the panel depending on the voltage to ground. You may not know this voltage, so it’s best to provide 4 feet. The panel must be easily accessible, so don’t install it too far above the floor; 4.5 to 5 feet is about right.
Can a subpanel feed another sub panel?
Answer: Yes. The main electrical service panel is where branch circuits originate. A branch circuit consists of the circuit conductors between the final over-current device protecting the circuit and the lights, receptacles and equipment supplied by the branch circuit.
What is the difference between a main panel and a sub panel?
The main panel is directly connected to the point of entrance to a building, and all sub-panels feed off that connection. However, the sub-panel provides a useful methodology for installing outlets that help you organize your electrical system into something more manageable.
Can you run a 100 amp sub panel off a 100 amp main panel?
Let me try and answer some of your questions. First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.
How big of a sub panel can I run off a 100 amp service?
However, NEC prohibits more than 42 circuits, so you can only choose between 20-42 breakers for a 100-amp panel. Breakers or circuit breakers act as a switch for cutting off power from the main electrical supply.
Can you run a 200 amp sub panel off 200 amp main?
Is feeding a 200A sub from a 200A main legit? Yes, and you don’t even need another 200A breaker. The 200A breaker alread present in the panel will suffice, and so you can use a subfeed lug kit as DrSparks advises.
