ETI/Richard’s offers an on site or at our factory a comprehensive instructional class on all models of protector that we produce. The classes consist of a basic understanding of what a network is and what makes it the most reliable underground network system available to date. Following an open lecture on the mechanical and electrical system for the switch under study the students attend a hands on lab that stimulates and hones the trouble shooting abilities for each attendee. Optimal class size is 10 to 15 people.
