Types. Electromagnetic interference can be categorized as follows: narrowband EMI or RFI , which typically emanates from intended transmissions such as radio and TV stations or mobile phones. broadband EMI or RFI , which is unintentional radiation from sources such as electric power transmission lines.

There are two types of ground-fault protection required by the NEC: 1) the GFCI and 2) the GFPE. A GFCI is intended to protect persons against shock and electrocution. As implied by its name, the GFPE protects equipment from damaging line-to-ground faults and is not intended for the protection of people.

2-Channel 5V Relay Module is a relay interface board, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on. It uses a low level triggered control signal (3.3-5VDC) to control the relay. Triggering the relay operates the normally open or normally closed contacts.

The two types of ladder control circuits commonly used are the 2-wire control circuit and the 3-wire control circuit. The 2-wire control circuit uses maintained contact devices to control the magnetic motor starter. The 3-wire control circuit uses momentary contact devices to control the magnetic motor starter.

The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding.

Variations in Hardware Components; A switchgear consists of switching devices that are needed for low to medium to high voltage electrical circuit. It is composed of parts like fuses, lightning arresters, circuit breakers, isolators, relays and disconnect devices that regulate the flow of electricity.
