Can a sub 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.
Is it OK to use a junction box?
Whenever you splice wires together while installing residential circuitry, the electrical code requires you to enclose the connections in a junction box. This safety measure prevents fires that can occur when the wires overheat and also protects people from getting shocked by live wires.
How far does a sub panel need to be from the main panel?
Installing a Subpanel and Choosing Cable

Can you use a panel box as a raceway?
A. Yes, cabinets, cutout boxes, and meter socket enclosures can be used as a raceway for conductors that feed through if the conductors do not fill the wiring space at any cross section to more than 40% [312.8], as shown in the Figure.
Where can junction boxes be used?
What are Junction Boxes Used for? Junction boxes can be used to connect additional sockets to circuits, add lighting points, extend circuits, and in general they are a way of getting power from an existing source and taking it somewhere else. They can also be used for repairs.
What is code for electrical junction box?
Securing Cables
Article 334.30 states that cables coming out of the junction boxes should be secured within 12 inches of the box in all boxes equipped with cable clamps. These cable clamps are not to be removed. 314.17(C) states that cables must be secured to the receptacle box.
Where can you put an electrical junction box?
Junction box covers must remain accessible; they cannot be covered with drywall or other surface material. A junction box is most often used where an electrical circuit branches off in two or more directions from a location where an outlet or fixture is not practical.

When connecting a switch to a circuit what should you always do first?
STEP 1: Disconnect the power source.
Skipping this part or doing it incorrectly could be fatal. Before you do anything else, ensure that no power is running along the circuit that you’ll be working on. That means going to the breaker box and switching off the breaker that controls the switch you intend to replace.
What is an electrical box for?
Electrical boxes, also known as junction boxes, enclose wire connections. They help protect against short circuits, which can cause fires. This guide describes the different types of electrical boxes, their materials and their applications. They come in many shapes and sizes to fit wherever you need them.
Where can you use a junction box?
