How do you torque a circuit breaker?
Quote from the video:

What are electrical outlets made of?
The receptacle is another name for the electrical outlet itself. Romex, or a nonmetallic cable, is made of three wires inside of a plastic sleeve or jacket. The three wires include the hot black wire, the neutral white wire and the grounding bare copper wires which connect to the circuit breaker panel.
How important is it to torque electrical connections?
Proper Torque for Loose Connections
Loose connections inevitably generate excessive heat, resulting in damage to equipment and potentially fires. In addition, when conductors are not making solid contact due to lack of adequate torque, you can have arcing and sparks, which can also lead to fire.

Quote from Youtube video: Hold the wires side-by-side grab the end with a pair of linesman pliers and twist clockwise twist them together like a candy cane. Don't leave one wire straight while you twist the other around.
Why electrical connections must be inspected regularly for tightness?
A loose or dirty connection has increased resistance which results in higher power losses. By simply tightening and cleaning electrical connections, you can lower these energy costs. When considered over a period of time, these energy losses can add up to quite a significant amount of money.
What torque should I use for screws?

What happens if you over torque a bolt?
Typically, an under torqued bolt will deform and be unable to provide as much clamping force as needed. An over torqued bolt will break.
Can I reuse torqued bolts?
Reusing nuts, bolts, washers, and other mechanical fasteners is generally never a good idea. If you have any doubts about a fastener’s condition, it is best to discard it in favor of new fasteners as that will always result in a stronger, more durable joint.
Why should you not overtighten screws?
One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.
How do you torque without a torque wrench?
Quote from the video:
Quote from Youtube video: Or even a long ratchet will work but something that's at least a foot long if you're going to be dealing in foot-pounds. You need your arm in a way to measure the exact amount of distance.
Is a torque wrench really necessary?
If you plan to do any major work on your engine or on some major powertrain components, you absolutely need a torque wrench. Overtightening cylinder-head bolts, for instance, can easily cause expensive damage and catastrophic coolant loss.
How do you choose the right torque?
Quote from the video:
Quote from Youtube video: So what we're going to do is we're going to rotate. This. Until our zero. Right here meets that hundred foot pound line right there.
