Can I put a junction box behind drywall?
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.
How do you splice a wire without a solder?
What you need: a roll of electrical tape and two wires whose ends have been twisted together. First, lay the twisted part of the wires onto a strip of electrical tape. Wrap the tape around the wires tightly 5-6 times, making sure to cover up all the wire. Give your connection a tug to make sure it is strong.
Can you run electrical wire through wall studs?
When running cable along the length of studs or joists, keep the cable to the center of each, leaving a 1 1/4-in. minimum clearance on each side of the framing member. When running cable through studs, drill all holes at the same height so that the cable is run level to the floor.
Should cables be protected in walls?
All electrical cables should be set into the walls at a minimum depth of 50mm if they are not mechanically protected. If it isn’t possible to chase the walls to that depth then the cables should be set deep enough so that metal capping can cover them and allow for plaster to cover that.
How do you run electrical wire without cutting drywall?
How to Install Wiring Without Cutting Drywall
What are the different methods of joining wires?

How do you use Wago connectors?
Quote from the video:
Quote from Youtube video: Use the guide on the back of the connector push. Your cable up the end of the guide mark. It with your thumb or finger take your wire strippers. And put them in line with the mark you made.
How do you tap into a wire without cutting it?
You simply want to strip back the insulation on the wire you need WITHOUT cutting any of the copper wires themselves. Then use a pointed tool to poke through the copper strands and make an eye. Then simply thread your new wire through the eye. Then close up the eye and wrap your new wire around it.
Can you splice into existing electrical wire?
Fortunately, no. Savvy electricians can splice wires together, safely adding the length they need to reach their destination.
Are t tap connectors reliable?
T-tap connectors are unreliable and don’t guarantee a secure connection. Posi-Taps provide ultimate wire penetration for a solid connection and a secure twist for reliable securement. They seem a bit expensive for the quantity given but they are worth EVERY DOLLAR.
What are splice connectors?
A splice connector is a vinyl plastic wire termination device that has a sharp metal insert which safely cuts through the plastic insulating jackets of two wires and crimps them together. The splice connector is then closed to securely hold the wire connections together.
How do I splice one wire to another?
Quote from the video:

How do you butt splice?
Quote from the video:
Quote from Youtube video: Make sure that the butt splice and the wire insulation are touching to reduce the risk of damaging the wire. So the stripped wire is inserted into one side of the butt splice.
Why is soldering better than crimping?
Crimping offers stronger, more reliable connections than soldering. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail. Most electricians will agree that crimping is also easier than soldering.
WHAT IS A crimp termination?
A crimp termination is performed when the device requires a contact or terminal. The wire insulation is stripped, and the contact or terminal is attached to the wire using a crimp tool. The tool crimps the contact or terminal onto the wire conductor.
What does crimped wire mean?
Crimping is a process used to join wire to wire or wire to terminal. Just as the name suggests, bonding occurs when one piece of metal is deformed and compressed tightly with another piece of metal.
