A Type T plug fuse is also known as what type of base?

1. Edison base

2. Bayonet base

3. Twist-lock base

4. Socket base

The correct answer is: Edison base

A Type T plug fuse is commonly referred to as an Edison base. This type of fuse is designed to fit into a standard socket, similar to the conventional light bulbs that use the Edison screw base design. The Edison base is characterized by its threaded design, allowing secure attachment and easy replacement in electrical fixtures. This terminology is important for home inspectors because it directly relates to identifying and understanding older electrical systems, many of which utilized this type of fuse. Recognizing the Edison base is crucial during inspections, especially when assessing the safety and compliance of the electrical systems in older homes. In contrast, the other options refer to different types of connectors or fixtures. The bayonet base uses a pin system for securing the bulb, the twist-lock base is used for higher voltage applications and provides a more secure fit to prevent accidental disconnection, and the socket base typically refers to the part of a fixture that houses the light bulb. Understanding these different bases aids home inspectors in evaluating a home's electrical setup and ensuring its safety and compliance with current standards.
