Manual Transfer Switches provide a cost effective means to provide temporary back-up power for emergencies. We install a wide assortment of portable generator manual transfer switches from smaller six circuit 20 Amp to ten circuit 50 Amp units. It works simply as rolling out your portable generator, plug in your generator cord to a power inlet connected to the transfer switch and switch power to the desired circuits you only need running.

Mk3 Electrical Enterprises installs and maintains several brands of Standby Generators for business & residential applications.

Unfortunately when a business or a residence experiences a power failure it is never during a convenient time. Typically it is during times of inclement weather activity, but that is not always the case. Power failures are also a result of our current aging electrical infrastructure that is becoming more vulnerable to the increasing demand on the electrical grid. It doesn’t matter the time of the year, even a short power failure can result in a loss of thousands of dollars or present a life threatening situation.
