Servicing of Grounded Products
The standard accepted color coding for grounding wires
is GREEN or GREEN WITH YELLOW STRIPE. These
ground leads are NOT to be used as current carrying
conductors. It is extremely important that the technician
replace any and all grounds prior to completion of the
service call. Under no condition should ground wire be
left off causing a potential hazard to technicians and
consumer.
Wiring
A good service practice is never route wiring over
terminals and/ or sharp edges. This applies to any wiring
without regard to the circuit voltage. Wire installation
material and thickness is designed and regulated for
electrical spacing purpose only, but cannot always be
relied upon because of possible cuts and/or abrasions,
which can occur during servicing.
WARNING
!
To avoid risk of electrical shock, personal injury or
death; verify the oven is properly grounded and
polarized.
Proper Grounding and Polarization of
120 Volts Wall Outlets
For the safety of our customers and the service
technician ALL appliances have a three–prong power
cord and MUST be connected to a properly polarized and
grounded wall outlet.
This information was written for those who do not
understand grounding and polarization of a wall outlet.
A 120 volt wall outlet must always be wired as shown
below.
Neutral (N) - This slot is
the larger of the two and
should be neutral (dead)
with respect to ground.
Hot (H) - This slot is
the smaller size and
should always be hot
(live) with respect to
neutral (N) and ground(G).
Ground (G) - The round hole connection
is for the grounding circuit. Behind the
cover plate a green wire should be
connected to this terminal.
G
N
H
Explanation
Polarization
–This means that the larger slot must be
neutral and the small slot must be hot (live).
Mispolarized
–The outlet is miswired so that the larger slot
is hot (live) and the smaller slot is neutral.
Grounded
–This means the round hole connection is
connected to earth ground through a connection to the main
power panel.
Ungrounded
–The round hole connection is not complete
to earth ground and/or the main power panel.
Test Procedures (2 Methods)
Method #1
Purchase and use a ground monitor which indicates a
correctly or incorrectly wired outlet by instructions
imprinted on the monitor body.
Method #2
Voltmeter - (Use scale over 125 Volts A.C.)
• Test A - "H" to "N" must indicate line voltage.
• Test B - "H" to "G" must indicate line voltage.
• Test C - "N" to "G" must indicate zero (0) volts.
If "N" to "G" indicates line voltage the outlet is improperly
polarized.
If "H" to "G" indicates zero (0) volts the outlet is not
grounded.
CAUTION
!
To avoid risk of electrical shock, personal injury or
property damage; wiring changes or grounding of wall
outlet are to be made only by a qualified electrician.
General Test Information
Most testing in the manual is conducted with an
ohmmeter using a multiplier scale of X 10k (k–thousand
ohms). When using this scale, it is important that your
fingers do not touch the metal parts of the test probes.
To do so will give a false indication of the ohm reading.
