You can run the conduit below your basement ceiling joists and avoid the fuss, anyway. You can also use metal conduit which gives a more ‘finished’ look if that’s what you care about. “feeder wires need to be in conduit for the whole run” – That’s not really true, in general.

Does sub panel wire need to be in conduit?

Re: Subpanel wire run



Individual THHN conductors must be run in conduit–either metallic or non-metallic, flexible or rigid. You could probably use SER instead, as long as it’s sheathed and contains four conductors: one for Leg A, Leg B, neutral, and ground.

Can I run a sub panel to my garage?





Build Your Garage Sub Panel



Use 1 1/4-inch PVC conduit for a 100-amp sub panel or 1-inch PVC conduit if the sub panel is 50 amps or less. Run the conduit from the garage to the main panel box. If concrete has not been poured in the garage, run conduit down into the ground on the inside of the garage.

How do I wire my sub panel to my garage?

Quote from the video:
Quote from Youtube video: Here. Then I connected the garage circuit breaker by attaching the neutral wire to the neutral busbar the ground wire to the ground bus bar and the hot wire to the circuit breaker.

How do you wire a detached garage panel?

Quote from the video:
Quote from Youtube video: Started out by removing the drywall above the main house the electrical panel to install the new wire that would lead out to the garage. Luckily.

What size conduit do I need for 100 amp sub panel?

Installation of 100 amp electric service or subpanel needs a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire inside a minimum 1.25 inch, schedule 40 or 80 PVC electric conduit for underground service.

Does a sub panel require 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.

Does a detached garage need a sub panel?

A 100-amp subpanel in a detached garage may be enough to handle high-draw appliances such as refrigerators. As for basic lighting or low-load electronic devices, a 50- or 60-amp subpanel in a detached garage may suffice.

How do you run electricity to a detached garage?

Quote from the video:
Quote from Youtube video: So this is what we're using to bring the electricity out to the garage. It's called UF wire which stands for underground feeder.

What does the NEC require for a detached garage?

At least one 120-volt, 20-ampere branch circuit shall be installed to supply receptacle outlets in attached garages and in detached garages with electric power. Code Change Summary: A new code section was added to require a 20 amp circuit for a dwelling unit garage.

What wire do I need to run a sub panel?



The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)

How far can a sub panel be from the main panel?

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. The cable you run from the main panel to the subpanel also depends on the amperage rating.

Can I run a sub panel from a sub panel?

Answer: Yes. The main electrical service panel is where branch circuits originate.

Can you run a 100 amp sub panel off a 100 amp subpanel?



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 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, …

Do you have to bond a sub panel?

Rule #3: In a subpanel, the terminal bar for the equipment ground (commonly known as a ground bus) should be bonded (electrically connected) to the enclosure. The reason for this rule is to provide a path to the service panel and the transformer in case of a ground fault to the subpanel enclosure.

How high off the ground does a sub panel have to be?

All electrical panels must have a minimum of 36 inches of clearance in front of the panel, 30 inches of clearance across the face of the panel, and a minimum of 78 inches above the floor from the top edge of the panel.

Can ground and neutral be on same bar in subpanel?



The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.

Why do grounds and neutrals have to be separated in a sub 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. Obvious shock hazard!

Can I tie the neutral and ground together?

No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.

Do I need a ground rod for a detached garage?

Yes, you need a grounding electrode (ground rod) local to the detached building. Connecting to reinforcing steel in the slab would have provided a very good grounding electrode, but if it’s already poured, that ship has sailed.
