Panel Building

UL508A certified custom electrical panel
building capabilities


Electrical panel building is an essential part of Sonic Corporation’s business

Because we specialize in the manufacture of liquid processing skids it is crucial that we’re able to engineer and fabricate our own electrical panels and cabinets. With our highly qualified UL508A panel building capabilities we can configure and wire complete cabinets for our own systems or for your own specialized use.
