In the event of a power outage, an automatic transfer switch
will start your emergency generator for you so that your home
or business operation can continue uninterrupted. Then, when
power is restored, the transfer switch shuts off your generator
automatically. Our automatic transfer switches range in size
from 104 amps through 1,600 amps and are ideal for home, office
and agricultural applications. They require electrical installation,
so you will need to contact your local electrician to do whatever
wiring is necessary. The charts below lists Asco and LakeShore
transfer switches. If you are interested in switch options
that aren't listed (such as service-entrance rated, NEMA 3R,
etc) please call our office for assistance.
