Physical dexterity, mathematical knowledge, a focus on safety, and facility with both hand and power tools are all necessities for any electrician.
An electrician's most frequently used pliers may comprise reaming pliers, needle-nose pliers, and side-cutting pliers. Electricians have different kinds of cutters, wrench, odometers, spare wires, and screwdrivers to undo and tighten various pieces of hardware.
Common causes of electrical injuries include making contact with power lines, failing to employ ground-fault protection, failing to use a ground path, poorly operating equipment, and poor use of extension and flexible cords.
