Outlets
Outlets can be built into equipment, embedded in walls, mounted on ceilings, etc. and when installed outdoors or where there is moisture, a cover may be used to prevent the ingress of water droplets and dust. The number and shape of plug outlets differ depending on the product, and they are used properly depending on the application and plug type. Many materials are made of resin or metal, and some have a earth terminal or retaining ground, and some have a built-in timer and illuminance sensor.
