The standard screw size for attaching a junction box to a surface is typically 1-1/4 inch to 1-1/2 inch screws, often #8 or #10 in gauge. The exact size may depend on the type of junction box and the mounting surface. Always check the manufacturer's specifications for the specific junction box being used to ensure proper installation. Additionally, use appropriately sized screws to avoid damaging the box or the mounting surface.

Yes, a junction box can be used as a pull box, provided it meets the necessary size and code requirements for pulling wire. The National Electrical Code (NEC) specifies that a box must be large enough to allow for the bending of conductors and to prevent damage during installation. Ensure that the junction box is accessible and properly rated for the application to maintain safety and compliance.
The screw size is a 6-32. This relates to diameter size of #6 and 32 threads per inch. The length for receptacles is usually 3/4 of an inch.
Can lights have a junction box attached to them. So yes.
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.

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.
The screw that attached a switch or receptacle to a device box or mud ring is a 6-32 machine screw. Cover plate screws are also 6-32's. A junction box like a 4" square box has 8-32 screws on opposite corners that attache the cover or mud ring to the box. Round or octagon boxes that light fixtures attach to typically use 8-32 machine screws as well.
The number of 12-2 wires that can be safely accommodated in a junction box depends on the size of the box and the wire size. Typically, a standard junction box can safely accommodate around 6 to 8 12-2 wires. It is important to follow the manufacturer's guidelines and local electrical codes to ensure safety.
This depends on the size of the wire and the size of the box. Look in article 370 of the NEC code book under box fill. If you are using a plastic box it will have info printed on the box. If you need a licensed electrician lyou can find an electrical contractor at www.contraxtor.com
Yes, the outdoor junction box is waterproof.
The fixture box should have a ground screw on the bottom of the box. Sometimes you have to move other wires out of the way to see it. Just reconnect the fixture ground wire to this screw.

The number of 12/2 wires that can be safely accommodated in a junction box depends on the size of the box and the wire fill capacity. In general, a standard junction box can safely accommodate around 6 to 8 12/2 wires. It is important to follow the manufacturer's guidelines and local electrical codes to ensure safety.
To install a light junction box in a room, you will need to follow these steps: Turn off the power to the room at the circuit breaker. Choose a suitable location for the junction box on the ceiling or wall. Cut a hole in the ceiling or wall to accommodate the junction box. Run electrical wires from the existing power source to the junction box. Secure the junction box in place using screws. Connect the wires to the terminals in the junction box, following the manufacturer's instructions. Install the light fixture onto the junction box. Turn the power back on and test the light to ensure it is working properly.
