What must a complete heating panel be provided with for connection?

1. Power adapter

2. Power strip

3. Branch circuit

4. Extension cord

The correct answer is: Branch circuit

A complete heating panel must be provided with a branch circuit for connection because a branch circuit is specifically designed to handle the load and ensure safe operation of electrical equipment. A branch circuit is a portion of the wiring system that extends from the final overcurrent device to the outlets or devices. It provides the necessary electrical supply directly from the breaker panel to the heating panel, ensuring that it receives the appropriate voltage and current as specified in its rating. Using a branch circuit is crucial, particularly for high-demand appliances like heating panels. This direct connection minimizes the risk of overload and electrical faults that could arise from less suitable connections, such as a power strip or extension cord, which are not designed for continuous high-load applications. Power adapters and extension cords can pose risks, including overheating or fire hazards, if improperly used with high-wattage appliances. A power strip, while useful for many applications, does not provide the level of protection or capacity required for a complete heating panel. Therefore, ensuring a dedicated branch circuit for proper and safe heating panel operation is essential.
