8. POWER TOOLS AND SMALL APPLIANCES
This test would also apply to other similar equipment that has a
line cord. For double insulated power tools, the megohmmeter
leads are shown connected to the power cord and to some metal
part of the tool (e.g. chuck, blade).
Note: The switch of the device must be in the “ON” position and
the main power should be disconnected.
MOTORS
AC-Disconnect the motor from the line by disconnecting the
wires at the motor terminals or by opening the main switch. If
the main switch is used and the motor also has a starter then the
starter must be held, by some means, in the “ON” position. In
the latter case, the measured resistance will include the
resistance of the motor, wire and all other components between
the motor and the main switch. If a weakness is indicated, the
motor and other components should be checked individually.
