How to Install and Wire a Sub Panel Ask The Electrician Summary: Electrical Sub Panel wiring considerations for the home complete with pictures. Careful planning for your Sub Panel with immediate and future load considerations will help you understand how to size your Sub Panel. This information will help as you consider a Sub Panel and its size. Sub Panel Electrical Wiring Done Right The sub panel can be located right beside close by the main panel or in separate areas, if it is not for an accessory building or for use in a workshop then it will most likely be close to the main panel. How to Run a Subpanel to a Detached Garage | Hunker In the sub panel, connect the red and black wires to the main lugs on the top of the main buss. Connect the white wire to the neutral bus bar, located along the side of the main bus, and connect the green wire to the ground bus bar, which is connected directly onto the sub panel. Installing an Electrical Subpanel | Better Homes & Gardens A subpanel connects to the main service panel with a thick three wire cable. The feeder breaker in the main panel acts as the main disconnect for the subpanel. Before installing one, consult with an inspector to make sure you do not overload your overall system. A subpanel has separate bus bars for neutral and ground wires and typically has no main breaker. It may not be labeled "subpanel" but instead be labeled "lugs only." How to Add a Subpanel (with Pictures) wikiHow Run the feeder cable from the main panel to the subpanel. The 4 wire feeder cable should be included with your subpanel and is a large black cable with 4 wires inside of it. With the main panel door open, insert the cable and slide it through the knockout opening. Then feed it into through the knockout opening on the subpanel. How to Install a Subpanel electrical online – Bare ground wire to a case ground lug, the white neutral wire to an appropriately sized lug on the now isolated neutral bar, and the red and black hot wires to the lugs of the main breaker in the subpanel. As is the case in the main panel, you are reverse feeding the main breaker, which then feeds power through to the panel’s hot buss ... How to Connect a Sub Panel from Main House Power | Hunker You connect the subpanel to the main panel via a double pole breaker with the proper amperage rating. Break the connection between ground and neutral in the subpanel. A panel is a solution for an overcrowded main panel and a way to avoid running multiple circuits back to the main panel. Sub Panel Grounding and Neutrals Ask the Electrician A second panel or sub panel should have the neutral and ground terminals or bars isolated from each other, this is why the main circuit feed to the sub panel must have 4 wires, with a dedicated insulated wire for the neutral and a separate wire for the ground. All the ground wires bond back at the main panel together with the neutrals. Reasons to Install a Subpanel in Your Home The Spruce Subpanels and main panels alike have specific rules that need to be followed according to the National Electrical Code (NEC). 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. If you can picture an invisible phone booth with an electrical panel on one wall, you'll have a good idea of what is required. Wiring a Subpanel Fine Homebuilding Both require properly sized entrance cable, from the main disconnect in the case of main panels, and from the main panel in the case of a subpanel. The conductor size depends on the amperage the subpanel’s main breaker can handle and the distance from the main panel. There are any number of online references to find that information.
