Along that same line, one might ask, How tight should an electrical connection be? The simple answer is, Tight enough to carry the maximum circuit current forever with- out overheating, arcing, or significant voltage drop. Unfortunately, that answer is no more useful than Lincoln's.

The only safe way to tighten the lug is to cut the power. If there is not a breaker or disconnect before the feeder wires you will likely have to have the power company pull the meter to kill the power. On the good side it should only take a few minuets to make the correction.

Each bolt or nut you tighten on your car has calculated torque values specifically designed for assembly. Both under torquing and over-torquing a bolt can have a catastrophic failure, therefore it is important to tighten each bolt or nut to the manufacturer's specified values. ...

The danger of too little torque on a connector is not something that can be ignored. A loose connection will lead to arcing, which can cause poor conductivity, overheating, and can even be a fire hazard! ... Conversely, a connection that is too tight can cause damage to connectors or to the wires themselves.

4. Fit the Socket on the Fastener. Align the socket with the head of the fastener the fit should be tight enough that you can loosen or tighten the ratchet.

Plug a light into a dead outlet on the circuit, and turn it on. Have someone watch the light while you remove the cover of the live outlet or switch and wiggle it with a wooden stick. If the light flickers, there is probably a loose connection in the outlet or switch.

Connections on either aluminum or copper should not be retightened after installation following manufacturers' installation instructions. ... Unwarranted re-tightening of screw-type connectors can lead to failure of the connection with either aluminum or copper conductors.

To fix the problem, turn off the power to the device, then disconnect the wires and either clip off the excess wire or strip off additional insulation so the proper amount of wire is exposed. Then, reconnect the wires to their screw terminal or wire nut.

Where a tightening torque is indicated as numeric value on equipment or in installation instructions provided by the manufacturer, a calibrated torque tool shall be used to achieve the indicated torque value, unless the equipment manufacturer has provided installation instructions for an alternative method of achieving ...

Loose connections allow energy loss, so inspecting electrical connections for proper torque can result in energy savings. It's important to remember that for properly torqued connections, you don't want them to be too loose or too tight. A loose connection is obvious, but a tight one that is now stripped is less so.

Loose electrical connections cause multiple problems in appliances, heat being the most common one. We've all seen burnt wire nuts in a dishwasher power junction box or on a dryer heating element. ... Even a resistance as low as 5 ohms can produce more than enough heat to burn up the connection and surrounding wires.
