Before first use
. After any repairs, and before placing back in service. After suspected damage, and before returning to use. Every 3 months [for exceptions see, 29 CFR 1926.404(b)(1)(iii)(E)(4)].
What is an assured equipment grounding conductor program?
Assured Equipment Grounding Conductor Program (AEGCP) is
specifically designed to cover all electrical cord sets and electrical receptacles that
are not a part of the permanent wiring of the building; including, any power tools and equipment that may be connected by an electrical cord and plug and made available for …
When using the assured equipment grounding program on cords and tools grounding conductors shall be tested for continuity?
Hand and/or portable equipment shall be tested
every three months
to assure continuity of the ground circuit and connection to the proper terminal. This procedure does not apply to double insulated tools.
What is an assured equipment grounding conductor program and how does it protect from electrocution?
An assured equipment grounding conductor program is an OSHA and NFPA 70E requirement that ensures the safety of temporary power cord sets (extension cords). The program is designed
to prevent shocks or electrocution by ensuring the ground wire is electrically continuous from the equipment being used to the source
.
Where an equipment grounding conductor is required it must be run with the?
Equipment grounding conductors must generally be installed with
the conductors of an AC circuit
by installing them in the same raceway, cable, or trench except in rare cases when EGCs are permitted to be installed according to Section 250.130(C).
What is assured grounding program?
The assured equipment grounding conductor program
covers all cord sets, receptacles
which are not a part of the permanent wiring of the building or structure, and equipment connected by cord and plug which are available for use or used by employees.
What can damage flexible and extension cords?
A flexible cord may be damaged by
door or window edges
, by staples and fastenings, by abrasion from adjacent materials, or simply by aging. If the electrical conductors become exposed, there is a danger of shocks, burns, or fire.
What two types of grounds are required by OSHA?
There are two kinds of grounds; both are required by the OSHA construction standard:
System or Service Ground
: In this type of ground, a wire called “the neutral conductor” is grounded at the transformer, and again at the service entrance to the building.
How often should the ground conductor be checked for continuity?
Continuity and resistance of grounding systems shall be tested immediately after installation, repair, and modification; and
annually thereafter
.
What circuits are not to be grounded?
Electrolytic cells are commonly used in the aluminum- and chlorine-processing industries.
Secondary circuits of low-voltage lighting system
must not be grounded, as indicated in Section 411.5(A). Also, low-voltage lighting systems for underwater pool lighting supplied by isolation transformers must not be grounded.
When must you inspect your tools and extension cords?
Before use or return to service, testing should be conducted on each piece of equipment
every three months
. A continuity test is needed to make sure the extension cord or power tool has a grounded wire.
Where can minimum clearance distance for working near powerlines be found?
This is the most important rule: Work at a safe distance from all power lines. The Occupational Safety and Health Administration (OSHA) requires that equipment be kept at least
10 feet away
from power lines with voltages up to 50kV.
What is Faith’s assured grounding color code for August?
| Assured Equipment Grounding Conductor Program Color Code | Month # Month Tested Color of tape(s) to apply to cord | 8 August Red + | 9 September Red + | 10 October Orange |
|---|
What size wire do you run to a ground rod?
The NEC code requires that a solid copper wire used to connect to a ground rod be either
#6 or #8 gauge
, depending on the size of your electrical service cable.
What are the acceptable colors of the grounding conductor?
The grounded (neutral) conductors must be identified with the
color white or gray
in accordance with 200.6 and equipment grounding (bonding) conductors must be bare, or identified in the color green, or green with a yellow strip if insulated in accordance with 250.119.
What color is the equipment grounding conductor?
Equipment grounding conductors can be bare, covered or insulated. If insulated and No. 6 AWG or smaller, equipment grounding conductors must have a continuous outer finish that is either
green or green with one or more yellow stripes
.
