Restrictions on Motor Size
An appliance may require three to six times its normal
running current in order to start. The
$XWR3RZHU
can handle
surges to 6000 watts for five seconds, which translates to a
locked-rotor-amp rating of no more than 50 amps. The
locked rotor amp may be specified on the motor nameplate as
“LRA” or “LRI”.
When considering appliances with large motors, follow these
guidelines:
•
Make sure that the motor’s LRA rating is no more than
50 amps. The
$XWR3RZHU
may not be able to start a
motor with a higher LRA, and the
$XWR3RZHU
will shut
down if the attempt is made.
•
Make sure the battery bank, DC cables and DC fuses are
capable of handling up to 600 amps DC for five seconds.
A weaker circuit may not be able to provide sufficient
power to the
$XWR3RZHU
to allow the
$XWR3RZHU
to
start up the appliance. Again, if the circuit cannot deliver
the required current, the system may shut down or the
fuse may open.
