The overtorqueing sometimes results in the failure (breakage and forceful scattering) of any of the items in the jury rig (e.g., socket, breaker bar, wrench, pipe) or of the components being worked on (e.g., nut, bolt, loadbinder), and when it does so, the fragments can injure workers in the line-of-fire.

Breaker bar. A breaker bar (also known as a power bar) is a long non-ratcheting bar that is used with socket wrench-style sockets.They are used to break loose very tight fasteners because their additional length allows the same amount of force to generate significantly more torque than a standard length socket wrench.
A receptacle with a bootleg ground. In building wiring installed with separate neutral and protective ground bonding conductors (a TN-S network), a bootleg ground (or a false ground) is a connection between the neutral side of a receptacle or light fixture and the ground lug or enclosure of the wiring device.
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
The three conductors are usually coloured red, black, and white. The white serves as a common neutral, while the red and black each feed, separately, the top and bottom hot sides of the receptacle. Typically such receptacles are supplied from two circuit breakers in which the handles of two poles are tied together for a common trip.
An interlock device is designed to allow a generator to provide backup power in such a way that it (a) prevents main and generator power to be connected at the same time, and (b) allows circuit breakers to operate normally without interference in the event of an overload condition. Most interlock devices for electrical systems employ a ...
Narcissists tend to be excluded in social circles because of their disruptive behaviors, and if they feel left out, their arrogant and aggressive behaviors will only intensify, a new study ...
Otherwise, it may be either inserted first into a ferrule, which is then inserted into the terminal, or else attached to a connecting lug, which is then fixed under the screw head. Depending on the design, a flat-blade screwdriver , a cross-blade screwdriver, hex key , Torx key, or other tool may be required to properly tighten the connection ...
