Humber/Ontario Real Estate Course 3 Exam Practice

What electrical component distributes electricity to various parts of a home?

1. Distribution Panel

2. Electrical Circuit Adapter

3. Ground Fault Circuit Interrupter

4. Main Circuit Board

5. Service Entrance Cable

6. Transformer Box

The correct answer is: Distribution Panel

The distribution panel is the primary component responsible for distributing electricity throughout a home. It acts as the central hub for electrical circuits, breaking down the incoming power from the utility into separate circuits that can be directed to various outlets, appliances, and fixtures within the home. Each circuit is protected by a circuit breaker or fuse, which ensures safety by preventing overloads and potential electrical fires. In the context of a home's electrical system, the distribution panel is essential for managing the flow of electricity and provides a way to disconnect sections of the home's wiring for maintenance or in emergencies. Other components, although important in their own right, serve different functions. For example, the service entrance cable is responsible for bringing electricity from the street into the home but does not distribute it within the house. Ground fault circuit interrupters are safety devices that protect against electrical shock by cutting off power when a ground fault is detected, and the transformer box steps down voltage for specific applications but is not involved in internal distribution.
