-ELECTRICAL REPAIR-

Things You'll Need:

Neon Tester
Tape
Continuity Tester
Screwdriver
---------------

RESET A CIRCUT
BREAKER

1. When a circuit breaker
trips, it moves about
midway between the full-on
and full-off positions, and it
will move back and forth a
little when you wiggle it.

2. To reset a tripped breaker,
push it to the full-off
position (opposite all the
other breakers in its
column), then to the full-on
position, and then let go
immediately.

3. If it trips again or does not
stay in the On position,
push it to the full-off
position and tape it over
until you've resolved
whatever's causing it to
trip.

TEST A LIVE RECEPTABLE

4. Plug the two probes of a
continuity tester into the
two vertical slots. If there
is power, the tester will
glow. Test both halves.
Some receptacles are
powered by two separate
circuits.
5. Alternatively, plug a neon
tester into the receptacle.

6. It analyzes the wiring, and
its lights identify the
problem.

Test for power at an
open outlet box

7. Shut off power to the
circuit at the service panel.
Remove the outlet cover
and remove the device (a
switch or receptacle), or
bend out the connected
wires and keep the ends
apart.

8. Test a device by probing
each terminal screw with
one lead from a neon
tester and probing a metal
outlet box or bare
grounding wire with the
other lead.

9. Test connected wires by
removing the wire nut
enough to expose bare
wire, then probing that wire
and either a metal outlet
box or the bare grounding
wire. Repeat the process
for every wire connection.

TEST A DEVICE FOR
CONTINUTY

10. Make sure the wire or
device isn't live. Use a neon
tester on wiring, or unplug
or disconnect a device.

11. Clip one lead onto one
terminal of a switch, for
example. Probe the other
terminal. The tester should
light with the switch in the
On position and, just as
important, should not light
in the Off position.

12. Probe the other terminal.
The tester should light with
the switch in the On
position and, just as
important, should not light
in the Off position.

TIPS & WARNING

Test a continuity tester's
battery and bulb by
touching the probe and clip
together momentarily. The
bulb should light.

A circuit breaker may have
a red indicator that signals
it has been tripped.

If a breaker tripped due to
a tool or machinery
overload, make sure you've
switched off or unplugged
that tool before restoring
power.

Never use a continuity
tester until you have
verified that there's no
current in the line.

If you know of or suspect
an unresolved problem that
has caused the breaker to
trip, do not attempt to
reset it until you've
investigated and corrected
the situation.
