1. bonding the process of connecting physically and electrically metal components of
an
electrical system not intended to carry electrical current to provide a
ground path for circuit breakers to clear ground faults
2. branch circuit conductors that begin at the circuit breaker or fuse and serve one or
more outlets
3. bus/buss bar heavy, rigid metal part of the panelboard where the circuit breaker or
fuses are
mounted
4. conductor wires
5. cable two or more conductors encased in sheathing
6. feeder conductor conductors from the service equipment or panelboard that supply
electricity to
another panelboard like a subpanel
7. grounding metal that is in direct contact with the earth to provide a ground for
elec-trode
electrical equipment
8. Grounding
a conductor that runs between grounding electrodes and an accessible
elec-trode
point downstream from where the grounded service entrance conductor
conductor
connects to the service drop
(GEC)
9. ground fault metal that should not be energized becomes energized; this current will
increase if not grounded and cause a trip
10. Lug a connection point where conductors are inserted and secured
11. Overcurrent fuse or circuit breaker
pro-tection

14. single phase electrical service that has 2 energized 120 volt conductors and one
electrical
grounded conductor
service
15. subpanel panelboard that receives power from an upstream panelboard
16. terminal bar metal bars associated with a panelboard on which neutral and equipment
grounding conductors (EGCs) are mounted
17. 120/240 volts what most single phase systems American homes use
18. 240 volts between 2 energized conductors and 120 volts between each
conductor and the grounded conductor
19. Out of date existing work does not need to be updated if it complies with the rules in
elec-trical ettect when installed, if it is still functioning properly
system re-
quirements
-must include a grounding electrode and a grounding electrode
20. grounding conductor
elec-trode
-20 feet of #4 rebar or #4 AWG bare copper wire encased in
system
concrete (ufer ground)
-galvanized steel pipe or rod or copper-coated steel rod driven at least 8
feet into the ground
-a metal water service pipe in contact with the ground for at least 10
feet
21. grounding
-1 grounding electrode is required but all accessible grounding
elec-trode
electrodes around a house must be bonded together using the
require-
ments same size wire as the grounding electrode
-newer homes a metal water service pipe may not be the only
grounding electrode, but if it is there it must be bonded to all other
grounding electrodes
