Testing breakers: Breakers were tested using a Multi -Amp MS-1A. As per
instructions breakers were tested using 300 % amperage. Breakers all tripped
within 15 seconds or less. Breakers that did not test correctly were replaced
with breakers that did test correctly. All breakers have been tested in 400
amp panel 3 and 200 amp panel panel 2.
Training was by Doyle Dickinson who has used this device for over 20 years.
He has a current Oregon Electrical Supervisor license originally received in
1950.
Lawrence Dickinson, a current Electrical Supervi for over 25 years
conducted the test.
Attached is a web page from Advanced Test Equipment Rentals. There are
several test companies that rent this equipment currently.
Service disconnect now have labels- "Service Disconnect"
The transformer is has been bonded to the frame.
An equipment ground wire has been added to the load side flex to the 200 amp
208 volt disconnect.

TEST PROCEDURE FOR THERMAL ELEMENT OF MOLDED CASE
CIRCUIT BREAKERS
1. Set-up MS-1A with:
a. POWER ON /OFF button in OFF position (red light out)
b, OUTPUT CONTROL knob at minimum, "0" position
C. ON-OFF -TEST switch in center OFF position
2. Connect one end of a high- current lead to one pole of circuit breaker.
Connect other end of this lead to appropriate COMMON terminal of test set.
If test current is in excess of 5 amperes, use common terminal
labeled ABOVE 5A.
If test current is 5 amperes or less, use Common terminal
i labeled 0 TO 5A.
I 3. Connect one end of second high - current lead to other side of same pole of
circuit breaker. Connect other end of this lead to output terminal labeled
0.3V, 200A (See SELECTION OF OUTPUT TERMINAL, page 2).
4. Use RANGE SWITCH to select ammeter range so that test current will be
read in upper 1/3 of meter scale.
5. Connect test set to suitable 120 -volt, single -phase power supply.
III 6, Press POWER ON /OFF button (red light should glow).
l 7. Rotate OUTPUT CONTROL knob clockwise and momentarily press and hold
i ,40"• ON- OFF -TEST switch in TEST position to observe current reading on ammeter.
Releose ON-OFF-TEST switch.

8. Continue to rotate OUTPUT CONTROL knob clockwise while jogging (repeat-
edly moving to TEST position and releasing) ON -OFF -TEST switch until desired
test current is reached. Suggested test current is three times (3x) the rating
of the circuit breaker. rR
If desired test current is not reached with OUTPUT CONTROL
knob at maximum clockwise rotation, return knob to zero and
trenifer output lead from terminal labeled 0 -3V, 200A to
terminal labeled 0-6V, 100A. Proceed with current adjustment
as in Steps 7 and 8. (See SELECTION OF OUTPUT TERMINAL,
page 2).
9. Connect together (short) the binding posts of test set labeled CONTACTS with
one light lead.
10. Set TIMER to zero by pressing timer reset button.
NOTE: Before starting test, allow time for the thermal element to
cool, otherwise incorrect tripping time may result.
1 T. Start test by pressing ON -OFF -TEST switch to TEST and release.
12. When circuit breaker trips, TIMER stops and output is de- energized. TIMER
indicates the total elapsed time of the test in seconds.
NOTE: Test current may decrease (fall off) during the test because
the resistance of the test circuit increases. Rotate OUTPUT
CONTROL knob clockwise to keep test current at desired
value.
13. Turn test set OFF by pushing POWER ON /OFF button.
14. Record test results on Test Record Card.
