How do you wire a sub panel?

In the subpanel, route the feeder wires, cut and strip them, and connect to terminals. Connect the black and red wires to the hot bus bars, the neutral wire to the main neutral terminal, and the ground wire to the ground bus bar. Run cable for new circuits into the subpanel and clamp the cable.

Can a subpanel be installed outside?

A subpanel plugs into the main panel by means of a double-pole breaker, and it cant exceed the amperage rating of the main panel. The subpanel enclosure must be securely attached to a wall or other stable surface with the fasteners recommended by the manufacturer. You can install it outside, but you must choose a panel approved for exterior use.

What is a subpanel?

What is a Subpanel? A subpanel (Remote Panel in NEC) is a smaller service panel derived from the main panel via two poles circuit breakers to securely distribute electric power to the other parts in the building, home, garage or any other specific applications in the premises.

How far should a sub panel be from the main breaker?

Before you begin installing a subpanel, shut off the main breaker in the service panel. Mount the subpanel about a foot away from the main service panel. Determine how far the wires will have to travel in the subpanel and pull wires (shown) or add cable and strip sheathing accordingly.

How to install a sub panel in a wall panel?

1 You may need to remove a knockout slug to insert the wires into the main panel. 2 There should be a black wire, red wire, white wire, and bare metal wire. 3 If you’re installing a subpanel in a separate room from the main panel, use a longer feeder cable to reach it.

What wire do I use for a sub panel?

The subpanel is fed-up by 2-Poles, 240V breaker at the main panel via two hot wires (L1 & L2), a Neutral wire “N” and Ground wire “G”. Keep in mind that there is no need to bond Ground with Neutral in the subpanel (as they are already bonded in the main panel).

How do you hook up a sub panel to a breaker?

Route and secure the sub panel feeder cable into the sub panel. Attach the hot wires (black and red or blue) to the main breaker lugs of the sub panel. Take the time to tidy up the wires and connections so that you can easily trace them back to their breaker if the need arises in the future.

How do you wire a sub panel to a bus bar?

Connect the other end of the wire in the subpanel in the same fashion. Then, connect the ground wire to the ground bus bar, tighten the screw to secure it, and connect the other end of the wire to the neutral bus bar in the subpanel. A bus bar is a metal strip or bar used to connect wires to power the panels.

What size breaker do I need for a sub panel?

Sub-panels generally do not have a main breaker in them; the main breaker for the sub-panel is in the main panel box. If you want your sub-panel to have a main breaker it will have to be smaller then a the breaker in the main panel box. The most common sub-panel for an outbuilding is a 60-amps breaker.

How big should a subpanel be?

The size of the subpanel depends on what you plan to connect to it, and it also depends on the capacity of the main panel. A subpanel plugs into the main panel by means of a double-pole breaker, and it cant exceed the amperage rating of the main panel.

What is a sub panel on a house?

A subpanel is a smaller service panel that enables power distribution to specific areas of your building or home. A subpanel is basically a satellite circuit breaker panel that extends the capacity of the main panel. A double-pole 240V circuit breaker at the main service panel usually feeds your subpanel with power.

How many subpanels can be installed with 200 amps?

You can install as many subpanels for the main panel of 200 amps as long as the combined demand doesn’t exceed 160 amps. Remember that a subpanel is simply a secondary circuit breaker that gets its power from the main panel. If you plan to have subpanels in your building, it will help know the exact number of these devices you need.
