General Use
This is the maximum current a conductor can carry under the conditions of use.
What is Ampacity?
If something is connected to establish electrical continuity and conductivity, we say it is this.
What is bonded?
This catch-all term is used for the conductors and equipment that deliver electrical energy from the utility, to the premises.
What is the service?
When something is rendered inaccessible by the finished walls of a building, we would refer to it as being this.
What is concealed?
When something is designed to be operated at a constant load for an indefinite amount of time, it would be given a rating of this.
What is continuous duty?
This is the name for the circuit conductors between the final overcurrent device protecting the circuit and the outlet.
What is a branch circuit?
This is an electrically conductive path from the point of a ground fault on a wiring system, through non-current-carrying conductors, equipment, or the earth, too the electrical supply source.
What is ground fault current path?
The main control and disconnect of the serving utility, consisting of circuit breakers, switches and fuses, is called this?
Service Equipment
An enclosure that is designed for surface or flush mounting, and is provided with a frame, mat or trim where you can hang a swinging door.
What is a cabinet?
When a component is electrically connected to a source of voltage, we refer to that component as this.
What is energized?
Any current in excess of the rated current of equipment, or the ampacity of the conductor is called this.
What is overcurrent?
This is the conductor used to connect the grounded conductor or equipment to a grounding electrode.
What is a grounding electrode conductor?
Designated by the serving utility, this is the location where the utility and premises wiring meet.
What is the service point?
This means something is recognized as suitable for a specific purpose or function as described in the code.
What is identified?
This means an item is constructed so that moisture will not enter the enclosure under specified test conditions.
What is watertight?
A branch circuit that supplies two or more receptacles or outlets for lighting and appliances.
What is a general purpose branch circuit?
This is a connection between two or more points of the equipment grounding conductor.
What is an equipment bonding jumper?
These are the overhead conductors between the serving utility and the service point.
What is the service drop?
The prospective symmetrical fault current to which an apparatus is able to be connected without sustaining damage exceeding defined acceptable criteria.
What is short-circuit current rating?
When something is protected to remove the likelihood of someone or something approaching to the point of danger, we say that thing is what?
What is guarded?
This part of an electrical systems main job is to carry or control electrical energy. (Not a conductor though!)
What is a device?
The connection between the grounded circuit conductor and the equipment grounding conductor can have these two names, depending on weather it resides in a service, or a separately derived system.
What is the Main Bonding Jumper and the System Bonding Jumper?
These are the conductors that connect to the service equiment.
What are the service entrance conductors?
When something is surrounded by a case that will prevent people from accidentally contacting energized parts, it is referred to as this.
What is enclosed?
When something is not readily accessible unless a special means of access is used, we say it is this.
What is isolated?
