Abstract: An insulating boot for use with an electrical device that is attached to a outlet box. The box is attached to wall studs and may hold one or more electrical device, such as snap or dimmer switches, electrical outlets, television cables, telephone jacks and the like. The boot is made of a non-conducting, elastic material in the form of a strip the ends of which adhere to form a loop that snap around the circumference of the device. A second strip follows a second circumference around the back of the device and attaches by adhering to the first strip at a position between the ends of the first strip so as to to interfere with the attachment of the two ends of the first strip. The insulating boot prevents the shorting of the terminal of a device against the grounded outlet box wall or against the terminals of an adjacent device.
