General Definitions
Connection of metal parts to establish electrical continuity and conductivity.
Bonded
kitchen countertop receptacles must be installed so that no point along the wall line is more than this distance from an outlet.
24 inches
This NEC article primarily governs the installation, design, wire methods, etc. of solar photovoltaic systems
690
this is the largest size air cooled generac generator currently available on the market.
26kw
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.
Feeder
In a dwelling unit, at least two of these are required to serve the kitchen, pantry, dining, and similar areas.
Small appliance branch circuits
This device converts DC power from the PV array to AC power to be compatible with the utility grid.
Inverter
A transfer switch prevents this dangerous condition when a generator is connected to a utility-fed panel.
Backfeeding
Locations protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture are this type of location
Damp
receptacles in dwelling unit habitable rooms must be installed so that no point along the floor line is more than this far from an outlet.
6 feet
PV system disconnecting means must be readily accessible and capable of disconnecting all current-carrying conductors except this one.
Grounded conductor
This type of transfer switch allows for the installation of circuit breakers and generator conductors all in the same panel.
Load center transfer switch
A 48 amp hardwired EV charger must be installed on this size breaker
60
An organization, office, or individual responsible for enforcing the requirements of a code or standard, or for approving equipment, materials, an installation, or a procedure is known as this.
AHJ
at least one outdoor receptacle must be installed at the front and back of a dwelling unit and must be accessible at or below this height.
6 1/2 feet
load-side connections or (backfed breakers) are only allowed when the sum of the ampere ratings of all overcurrent devices supplying power to a busbar does not exceed this percentage of the busbar rating.
120%
To allow for expansion as temperatures fluctuate, propane tanks are filled to this percentage.
80%
two or more ungrounded conductors that have a voltage between them, and a grounded conductor that has equal voltage between it and each ungrounded conductor are this type of circuit
MWBC
When determining the maximum number of receptacle outlets permitted on a branch circuit in a commercial occupancy, the load per outlet is calculated at this volt-ampere rating
180
In a DC-coupled system, the PV array charges the battery bank through this device, rather than routing power through the inverter first.
Charge controller
The Fuel shut off valve must be installed in a readily accessible location and within this many feet of the generator fuel inlet
6 feet
