Design Guides

This design guide is intended provide typical electrical installation scenarios with each scenario to include compliance to standards. As their are many ways of complying with standards,this design guide is prepared to suit the minimum standards requirements.

While design principles equally applies to larger and more projects, this design guide will not attempt to address the design needs of those installations.
