Question

What is a large single panel, frame, or assembly of panels on which are mounted on the face, back, or both, switches, overcurrent and other protective devices, buses, and usually instruments? These assemblies are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets?

Answer 1

The subject in question is an electrical panel or distribution board, used to distribute electricity and protect circuits with circuit breakers and GFCI outlets.

Step-by-step explanation:

The item described in the question is known as an electrical panel or a distribution board. This panel is crucial for distributing electricity to various circuits within a building and houses circuit breakers and potentially ground fault circuit interrupters (GFCIs). Circuit breakers are designed for a maximum current and can be reset after tripping, providing protection for electrical circuits by opening quickly to prevent overcurrent situations. GFCIs are another type of protective device commonly found in high-moisture areas like bathrooms and kitchens, which trip rapidly upon detecting changes in the magnetic field caused by a ground fault. Assemblies like electrical panels are integral to ensuring electrical safety and managing the cost of electricity by appropriately routing and protecting the power supply.
