Dairy Farms need IPEX too

Featured Case Study

Dairy Farms need IPEX too

The Pelletier dairy operation near La Pocatière, Québec needed a wiring and panel upgrade that would be sturdy enough to manage the demands of an 80-cow dairy herd. This is where the IPEX Scepter® JBoxTM and new Hinged Cover Scepter® JBoxTM junction boxes came in.
