Splices and termination are made in junction boxes because of safety. The weakest part of any circuit is the place where two or more wires are joined together. Because most home splices are of a mechanical nature they an become loose or just fall apart. A loose connection in a circuit that is carrying a high current will create heat through the resistance formed by the loose connection. Heat can cause combustion. Be retaining the heat or combustion in a closed container such as a junction box it contains the fault to a local area. Some electrical faults can create a shower of sparks that if not contained could cause the surrounding materials to ignite. Always keep the overs on junction boxes and never get into the habit of making open wire splices just because they work. Safety first.

Do you need a junction box for each light fixture?
Can lights have a junction box attached to them. So yes.
How do you size a junction box for an angle pull an a straight through pull?

Can you run a 240v wire from the electrical panel then put a junction box to run it where you want?
A 240 volt wire is the insulation factor of the wire. If you mean a 240 supply source from a distribution panel to a junction box then the answer is yes. You have to keep in mind that the box has to be accessible, meaning that you can get to the box to check the splice within the box. Don't bury the junction box behind the wall board.
Do wire nuts have to be inside junction box when installing porch lights?
The wire nuts do not have to be inside the junction box. They must, however, be as tight as possible to keep moisture from inside the light fixture.
What is the benefit of installing a junction box on the outer wall of a house?
You can use the junction box to send power outside to another building as long as you do not overload the circuit. Other than that there is no real benefit.
EXPLAIN WHAT WIRES DO IN A RECEPTACLE?
Wires bring the voltage source to the junction box of the receptacle. At this point they are terminated under the screws of the receptacle. With the receptacle screwed to the junction box and the cover plate installed the outlet is ready to be used. The last thing to do is turn the breaker back on to energize the receptacle.
How do you wire two light fixtures?
The lighting fixture should have all of the bulb's leads brought to a central point in the fixtures junction box. All of the black wires from the bulb's socket will be tied together. The same applies to the white wires from the socket.The white wires are tied into the lighting circuit's white neutral wire and the black wires are all connected to the "hot" supply wire. Once these connections are made, the fixture can be bolted to the ceiling junction box.
How do you size a junction box?
To size a junction box, you should determine the number and size of conductors entering the box, add the volume of any devices or fittings inside, and then select a junction box with a volume that accommodates all these components. Follow the NEC guidelines for minimum box sizing requirements based on the number and size of conductors. Always choose a junction box that meets or exceeds these requirements to ensure proper installation.

Do you need a junction box for each light fixture?
Can lights have a junction box attached to them. So yes.
How do coil wires come out of the single phase motor?
The coil wires of a motor are terminated on a terminal block in the motor's junction box. This allows for easy connection to the supply voltage through push on wire ends or lugs.
What is junction box?
A junction box is a container that holds electrical connections. The idea of a junction box is usually to keep wires safe, secure and free of dust, dirt and damp. A junction box is usually built within the layers of a wall so that all wires are concealed and the build looks neat and tidy.

In what situations does a junction box need to be weatherproof?
A junction box needs to be weatherproof if it is located outside. These junction boxes always need to be weatherproof since they are constantly exposed to rain and the elements.
Are junction boxes normally used in wiring the first floor of a house?
Yes, junction boxes are commonly used in wiring the first floor of a house to safely connect electrical wires and protect against electrical hazards. They provide a housing for spliced wires and connections, ensuring that the electrical system is secure and up to code.
How does one remove access panels from an electrical junction box?
Removal of an access panels from an electrical junction box depends on the type of junction box in question. Regardless of type, the first step in the removal should be the cutting off of the power main to the box itself.
Can a 240V wire be run from the junction box and not the service box?
Yes, a 240V wire can be run from a junction box that is connected to the service box. The junction box serves as a point where circuits branch off, so the 240V wire can originate from there rather than directly from the service box. It is important to ensure that all electrical work is done following local electrical codes and regulations.
