FAQs About Power Distribution Equipment

How does a mixing box work?

• A mixing box serves several functions such as controlling temperature, humidifying or dehumidifying air and cleaning and circulating air. Recirculating tempered air can reduce energy costs. An air mixing box is typically a self-contained unit installed directly into the ductwork, although it can be attached to a residential-style furnace or air handler.

What is the main purpose of an economizer?

• As the name implies, economizers are built to reduce energy consumption by utilizing the outdoor air to help with indoor cooling.

How does a generator transfer switch work?

• A transfer switch acts as a miniature circuit breaker panel that draws electricity from the generator instead of the original power source. When you need to draw power from your generator, in the case of a power outage, for example, you plug your generator into an outdoor outlet that connects to a transfer switch located inside. Without a transfer switch, you’d need to run multiple outdoor-rated extension cords from your generator into your business or jobsite — hardly an ideal alternative.
