Abstract: An insulator band, electrical wiring system, and kit for preventing shorting of electrical connectors. The system and kit of the present invention each utilize an insulator band that is manufactured of an insulating material, dimensioned of sufficient width to cover the terminals of the switch or outlet, and sized to provide a sufficient elastic force upon the switch or outlet to maintain it in position, while preventing breakage or springing from the switch or outlet. In operation, the wires are extended through the band and are connected in the normal manner to the switch or outlet. The band is then slid back over the wires, stretched over the switch or outlet, and positioned to cover the terminals of the switch or outlet. The switch or outlet is than installed into the outlet box in the in the normal manner. When the switch or outlet needs to be removed or replaced, the band is slipped back off the wires and may be reused once a new outlet or switch is installed.
