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.

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.
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.
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.
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 size a junction box?
There is no minimum height for junction boxes per NEC. Any use of a junction box that would be subjected to harsh conditions because of its height would have to be rated for the condition. Personally, in outdoor areas, I like to keep boxes at least 18" above grade in areas that get snow.
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.
Are junction boxes normally used in wiring the first floor of a house?
The area of a home has nothing to do with wear a junction box is placed. A junction box is placed wear a junction box is needed to split a circuit. any splice SHALL be in a junction box a junction box SHALL be accessable
Can a 240V wire be run from the junction box and not the service box?
Junction box for what? Do you mean a sub panel?
When do you use a conduit bushing?
A conduit bushing is used when a conduit is terminated in a junction box or enclosure. Its purpose is to provide a smooth rounded surface so that when the wire is pulled into the conduit the insulation on the wire will not be damaged.

Do you need a junction box for each light fixture?

How do you add another porch light to an existing switch?
Piggyback off the box for the existing light. Run a wire from the existing junction box to a new junction box (which is placed wherever you want the new fixture). Then, in the existing box, connect the wire coming from the switch, the wire for the existing fixture, and the wire for the new fixture together using wire nuts. Wire up the new fixture, and presto, you have two fixtures on a switch where there was only one before.
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.
