TYPES OF ELECTRICAL WIRING DEVICES

• Wiring devices - Single discrete units of electrical distribution systems which intend to carry but not utilize electric energy.
• Wiring Devices - Are electric devices that is used to control and provide connection points for low voltage outlets, lighting systems, and appliances.
• PEC - Philippine Electrical Code
• NEC - National Electrical Code
• Device - A unit of of an electrical system that is intended to carry, not utilize energy
• Types of Wiring Devices:

  • Receptacle
  • Switches
  • Conductors
  • Contactors
  • Relays
• Conductors - Substance or body that is capable of transimitting energy
• 3 Types of Conductors:

  • Bare Conductor
  • Covered Conductor
  • Insulated Conductor
• Bare Conductor - Conductor with NO insulation.
• Covered Conductor - Conductor with insulation but the insulation is not recognized by the code as an electrical insulation.
• Insulated Conductor - A conductor that is insulated and its insulation is recognized by the code as an electrical insulation.
• Switch - Device for making, breaking, or rearranging the connections of an electrical circuit.
• Types of Switch:

  • Single Switch
  • Three-way Switch
  • Four-Way Switch
  • Timer Switch
  • Sensor Switch
  • Dimmer Switch
• Single Switch - Most commonly used to control one or more lights from a single location.
• Three-way switch - A single switch having 3 terminals.
• Four-way Switch - An electrical switch in which a light may be turned off in 3 or more places.
• Timer Switch - Switch device that can be set to turn off at a certain time.
• Sensor Switch - Senses heat, light, sound, etc. Then it reacts to it.
• Dimmer switch - Allows you to control the brightness of the light.
• Receptacles - Contacting devices installed at an outlet for connection
• Types of Receptacle:

  • Duplex Receptacle
  • Straight Blade Receptacle
  • Floor Box Receptacle
• TR Receptacles - Have a built in shutters that need to have equal pressure from both prongs in order to fit inside.
• Duplex Receptacle is the same as TR Receptacle.
• Straight Blade Receptacles - Cover the full range of residential, hospital, industrial, construction, and commercial grades to meet any application.
• Floor Box Receptacle - An electrical outlet set flush with a floor are the ideal solution for your convenience for your residential needs.
• Contactor - Are electromagnetically operated switches that provide a safe and convenient means for connecting and interrupting branch circuits.
• Relays - Are used as auxiliary devices to switch control circuits and large motor starter and contactor coils.
• Wiring devices are defined as single discrete units of electrical distribution systems which are intended to carry but not utilize electric energy.
• Wiring devices are electical devices used to control and to provide connection points for low voltage outlets, lighting systems and appliances.
• PEC - Philippine Electrical Code
• Device - A unit of an electrical system that is intended to carry or control but not utilize electric energy.
• Path Devices - Devices which serve as path of elecrical current of the wiring system like wire conductor and all parts of the ciruit that has a low resistance.
• Control Devices are devices which can regulate the flow of current.
• Control Devices - They can make or break the circuit.
• Lighting Switches are common examples of control devices
• Fault Devices are devices which can immediately detect any fault in the wiring system.
• Switches - These are electrical components that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.
• Relays are switching devices used in any control circuit for checkinga condition or multiplying the number of contacts available.
• A relay consists of at least two contacts and an excitation coil
• Relays are used for switching of control circuits and cannot be used for power switching with relatively higher ampacity.
