There is no restriction on different size wires being spliced in the same junction box. If your question involves splicing 8ga. to 10ga, this also is not a problem so long as the circuit allows for 10ga wire.

∙ 10y agoYes, as long as the junction box will remain accessible at all times and the wires are held together with an approved #10 plastic wire nut. Also tape the wire nut up securely after tightening it down. Be sure and place an approved cover over the junction box.

Can you mix aluminum wire with romex in a junction box?
No, do not mix aluminum wire with copper wire.
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 type of prewire for a ceiling fan light?
The pre wire for a ceiling fan light should be made with a three wire cable. This cable will have a red, black, and white wire as main conductors. This cable will also have a bare ground wire. This wire should be strung between a two gang switch box to the fixture junction box. This pre wire allows the supply to be either fed to the two gang box. From the two gang switch junction box, one side will be used for the light in the fixture and the other side of the switch junction box, itwill be used for the fan portionin the fixture.
When is it required to bond a junction box?
If a junction box is part of an electrical conduit system then it is required to be bonded so as to make the whole electrical conduit system continuously conductive.
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?
How to extend a wire if an existing wire is short in the junction box?
The answer depends on what type of access you have to the junction box. The wire external to the box may have some slack that can be brought into the box. If everything is tight you will probably have to install one or more additional junction boxes or rerun wire from electric panel. As an example assume that the short wire has no external slack, but you can install a new junction box near the other box and in the path of the short wire. 1. Pull the short wire from existing junction box. 2. Install new box in path of short wire so more slack will be available in the additional junction box; and pull wire into new box. 3. Run a wire of the same size from new to old box and re-splice any connections for original short wire or new connections; and connect this new wire to the original short wire in the new box. Make sure you follow all code requirements for your locale.

How do you extend an 240v wire circuit 2 feet longer?
If you do not add a junction box it looks like new wire all the way from the old junction box with new wire that is longer. It's a tough place to be.

How do you extend romex wire you moved an outlet you need to extend and connect?
You need to splice the extension Romex, using wire nuts, inside a covered junction box made for the purpose. If you can do it within the original outlet box you can put a blank cover on the box. If not you may have to install a new "old work" box in wall. If you can get to wire in attic or basement you could put the junction box in one of those locations. The junction box must be accessible so you can't bury it in the wall.
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 you find the starter wire on an 85 GMC sierra 4x4?
A tiny 2-prong junction box on the firewall. one wire comes to it from the Ignition, & the other wire goes out from it to the starter. If you take a jumper wire from the positive on the battery & touch it to the post on the junction box where the starter wire comes out, with the key on, It should start the truck. If it doesn't, you need a new starter.
Are junction boxes used to wire exposed portions of a basement?
Any splice or termination to a device has to be done in a junction box. Wire splices are the critical and most likely point in a circuit where a fault can occur. The purpose of the junction box is to suppress the fault to to the confines of the box. This usually is enough protection to cause any fires that may be started from the electrical fault from spreading to other surrounding combustible surfaces.
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
