The ASCO service entrance rated automatic transfer switch combines a nec article 230 service entrance, and a automatic transfer switch in a space saving, easy to install package.
All buildings require a service entrance disconnect and over current protection device to be installed in between the utility and the building main distribution panel.
in some instances it makes sense to combine the automatic transfer switch with the service entrance disconnect. space is often a consideration and the installed footprint of the asco service entrance rated automatic transfer switch is much smaller than a separate automatic transfer switch and a service entrance breaker.
WE stock asco service entrance rated automatic transfer switches in many of the common sizes and voltages. for units that we do not stock, we can have the factory build a service entrance rated transfer switch to your exact specifications. this is normally a several week process, so please plan ahead.
every asco service entrance rated transfer switch has the exact same features as the 300g or the 185 series switch that they are based on. they can be equipped with the same accessories as well. the only difference is that there is a utility side circuit breaker installed in the switch enclosure.
