PART 2 – PRODUCTS (NOT USED)


3.1 EQUIPMENT TO BE TESTED

A. Section 16140, Wiring Devices:

1. Receptacles or Outlets

a. Ground Fault Circuit Interrupters (GFCI)

i. All GFCI outlets and protected outlets will be tested individually to

ensure they all meet protection requirements. A full GFCI test involves

the Test/Reset Button Test, Wiring Test and GFCI Circuit Challenge.

(a) Test/Reset Button Test:

(1) Ensure the energized circuit can be appropriately de-

energized.

(2) It is preferable to have a light, a fan, or a circuit tester connect

to the outlet to ensure the energization status of the circuit.

(3) Press the Test Button.

(4) The Reset Button should pop out. If it does not, proceed to

step (8).

(5) If the Reset Button pops out, check to ensure the electrical

equipment has become de-energized. If the electrical

equipment has not de-energized, proceed to step (8).

(6) If the electrical equipment has de-energized, press the Reset

Button. The Reset Button should stay reset and the electrical

equipment should re-energize. If the Reset Button does not

reset or the electrical equipment does not re-energize, proceed

to step (8).

(7) Repeat steps (3) through (6) with the light, fan, or circuit tester

plugged into the other receptacles.

(8) If the outlet fails any part of the Reset Button test, either the

outlet is miswired or needs to be replaced. If the repair cannot

be accomplished immediately and the outlet must remain in

service, place a caution label over the outlet to prevent usage

until the repairs or replacement are completed. Once repaired

or replaced the outlet must be fully tested before use is

allowed.

(9) When testing slaved outlets, repeat steps (3) through (8) with a

device plugged into the slaved outlet. Use the Test and Reset

Buttons on the GFCI that provides protection for the outlet to

perform the Test/Reset Button Test.

(b) Wiring Test:

(1) Acquire an accepted wiring test similar to the Greenlee GFCI

Circuit Tester with a wiring tester, catalog number 5708,

NAED/DCI# 78-3310/34523.

(2) If using a combination GFCI/Wiring Tester, set the nominal

leakage current knob to zero mA.

(3) Plug the tester into a receptacle on the outlet to be tested.


SECTION 16080



(4) Check the tester display to ensure proper wiring.

(5) If the wiring is improper and cannot be immediately repaired,

proceed no further, cover the outlet with a caution label until

the outlet has been properly wired and then repeat the tests

prior to allowing the outlet to be used.

(c) GFCI Circuit Challenge:

(1) Test the current that causes the GFCI to trip.

(i) Turn the current selector knob to the next higher current

setting;

(ii) Wait for the test light to flash;

(iii) If the GFCI trips out;

Reset the knob to zero current;

Press the Reset Button on the GFCI the outlet the

GFCI is wired to or the GFCI circuit;

Check for test lights to indicate the circuit is re-

energized;

Remove the tester from the outlet.

(iv) If the circuit does not trip out, repeat steps (i) through

(iv).

(v) If the GFCI fails to trip within 4 to 7 mA and the GFCI

cannot be currently replaced, proceed no further, place a

caution label over the outlet, indicate faulty GFCI and

once the outlet has been replaced repeat the tests prior

to allowing the outlet to be used.

(2) After the GFCI has tripped, repeat the tests in (a), (b) and (c)

for the other receptacle (on a 2-receptacle GFCI outlet) and

all GFCI protected outlets.

(d) Placing a Test Sticker:

(1) If the outlet passes all of the above tests, place a GFCI test

sticker on the outlet cover with the following information:

(i)The test date;

(ii) The tester’s initials and company;

(iii) The current level where the interruption occurred;

(iv) The wiring status;

(v) And the number of the outlet (to distinguish the GFCI

protected outlets from each other for documentation

purposes).
