Can I run a sub panel off of 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.

Can you splice subpanel wire?





Quote from the video:
Quote from Youtube video: Long as the splice.

Can you run 2 sub panels off the main panel?

You can add as many subpanels as you need providing the combined electrical demand is below 160 amps. If all the circuitry was operating at once, the electrical service could become overloaded.

Can you run a 100 amp sub panel off a 100 amp sub 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.

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.

How many breakers can I put in a 100 amp panel?





20 circuits

Typical 100-amp panels have 20 circuits, meaning they can handle 20 full-sized breakers. 20/24 panels can hold 16 full-sized and 4 twin breakers (24 circuits in total).

Can you splice in a panel box?

So basically yes, splices are FINE in a breaker panel. And, in fact, they aren’t uncommon during box replacement, when getting a clean layout may require a few splices. Splices in the panel are also common when installing transfer switches for generators.

Are wire nuts allowed in breaker panel?

Wire splicing and pigtailing are allowed in a breaker panel, and these connections are expressly permitted by NEC 312.8 (A). It may look a little untidy at times, but a breaker panel with many wires, wire nuts, splices, and pigtails can be a completely safe and compliant breaker box.

Can a panel be used as a junction box?



As long as there are overcurrent devices in a panel it cannot be used as a junction box. Most AHJ’s will allow you to use wirenuts and another piece of wire to lengthen a conductor – such as an existing neutral that isn’t long enough to reach a now required AFCI.

Does a subpanel need a ground rod?

Yes, any sub panel outside of the main building requires it’s own ground rod and a ground wire back to the main building. And yes, a sub panel in the same building as the main does not need a ground rod – only the ground wire.

How far can a subpanel be from the main panel?

The right feet would be between 4.5 to 5 feet.



The cable running from your main panel to the subpanel depends on the amperage rating. For instance, for a 30A panel, use a 10 AWG, three-wire conductor.

Can you feed a 100 amp sub panel with a 60 amp breaker?



You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.

How many breakers can you put in a 60 amp sub panel?

Modern 60-amp electrical panels are purpose-built as sub-panels and generally only have 8 to 10 slots available for circuit breakers.

What size wire do I need to run 60 amps 100 feet?

4 AWG

What size wire should I use for a 60 amp subpanel? You can get away with 6 AWG when you have a short run of wire, however, due to voltage drop, if you ever decide you want to go more than 100 feet then a 4 AWG is the size you should choose.

Can I run a 100 amp sub panel off 200 amp main?



Of course you can, you can add the 100 amp breaker to your 200 amp as long as it isn’t overloaded, to start adding the subpanel you must first calculate how many yards it will be from the main panel to the subpanel, there is a formula that calculates how much friction will be on the wire at the connecting distance, …

Can breakers add up to more than Main?

It is very common for the sum of the branch circuit breakers to add up to more than the main circuit breaker. The engineer that originally designed the building and electrical system understood that the loads were intermittent, and very unlikely to be maxed out at the same time.

Does a subpanel need a main breaker?

The subpanel may be equipped with a main breaker to allow for power interruption without having to go back to the main panel, but it is not required to have a main shutoff circuit breaker, since the feeder breaker back in the main panel serves this function.

Can you add a second electrical panel?

When a breaker panel becomes overcrowded with circuits, you may need to install a subpanel. This subpanel actually becomes another circuit in the main breaker panel. Tying this second breaker box into the house circuitry is as simple as adding another breaker to the main panel.

How do I add a subpanel to my electrical panel?



How to do it

  1. Mount Subpanel wiring. Mount Subpanel. Mount the subpanel about a foot away from the main service panel. …
  2. panel ground bus bar using screwdriver to ground wires. Plan Route. …
  3. Connecting Feeder Breaker Wires. Strip Wires. …
  4. Subpanel Hot Bus Bar. Connect Wires. …
  5. Subpanel New Circuit. Finish Connecting Wires.


Can you have 2 main panels?

If you are in the US, then the answer is yes. The main electrical drop has to be sized for both panels and each panel should have its own utility meter. All NEC codes must be conformed to. You need to consult your local government to see about local codes as well.
