What does the NEC consider a device?

(CMP-2) Device. A unit of an electrical system, other than a conductor, that carries or controls electric energy as its principal function. (CMP-1) Disconnecting Means. A device, or group of devices, or other means by which the conductors of a circuit can be disconnected from their source of supply.

What is a device according to the NEC?

Device. A unit of an electrical system that carries or controls electric energy as its principal function. Disconnecting Means.

Is a device or group of devices that govern?

Controller. A device or group of devices that serves to govern, in some predetermined manner, the electric power delivered to the apparatus to which it is connected.

How does the NEC define an outlet?

An outlet is defined as “A point on the wiring system at which current is taken to supply utilization equipment”.

Is a disconnect switch considered an outlet?

A: The disconnect switches are not considered “outlets”.

What are the example of protective device?

Examples of overcurrent protection devices are many: fuses, electromechanical circuit breakers, and solid state power switches. They are utilized in every conceivable electrical system where there is the possibility of overcurrent damage.

What is the difference between outlets and receptacles?

A receptacle is a set of slots into which a plug enters.

You wouldn't be wrong in calling it a socket. An outlet, on the other hand, is the box on which the slots sit. You can have multiple receptacles on a single outlet.

Is a device or group of devices or other means by which the conductors of a circuit?

Disconnecting means. A device, or group of devices, or other means by which the conductors of a circuit can be disconnected from their source of supply. Dust tight. Constructed so that dust will not enter the enclosing case under specified test conditions.

What is a feeder NEC?

Feeders, as defined in Article 100, are all circuit conductors between the service equipment, the source of a separately derived system, or other power supply source, and the final branch-circuit overcurrent device.

What is Article 100 of the NEC?

Article 100 defines a Grounded Conductor as – A system or circuit conductor that is intentionally grounded. ... And that in spite of this, Grounding Conductors are not considered Grounded Conductors by the NEC.

Is a three way switch a device?

Three-way switches allow you to operate a light, or device such as a ceiling fan, from two different locations. That's why a 3-way circuit always involves two 3-way switches. Watch our video for a straightforward guide to understanding how a three-way switch works – theoretically.

What article in the NEC distinguishes between an outlet and a receptacle?

The Code In Focus-- Article 210 - Branch Circuits. 210-21(b) Receptacles A “Receptacle,” as defined in Article 100, is a contact device installed at an outlet for the connection of an attachment plug. The words “receptacle” and “receptacles” appear quite often in the National Electrical Code (NEC).

Is there a difference between GFI and GFCI?

GFCI vs GFI. Ground fault circuit interrupters (GFCI) and ground fault interrupters (GFI) are the exact same device under slightly different names. Though GFCI is more commonly used than GFI, the terms are interchangeable.

Does a GFCI count as a disconnect?

A GFCI that has buttons marked off and on is permitted to be used as a motor controller and as a disconnect, but if you need lockable disconnect, it is not suitable.

Is a light fixture considered an outlet?

Luminaire is now the main term and fixture(s) or lighting fixture(s) follow in parentheses. ... A lighting outlet is an outlet intended for the direct connection of a lampholder, a luminaire or a pendant cord terminating in a lampholder. Luminaires can be ceiling-, wall- or even floor-mounted (See Figure 2).

What do electricians call disconnecting means?

Electrical disconnects are switches that isolate all wiring in a home or other building from the source of power, typically the utility power service. Also called the service disconnect, this is the first disconnect device after the utility meter.
