This exercise to demonstrate an estimating strategy of developing cost elements per electrical assembly. In this assignment, you will develop a unit cost estimate for two assemblies, one for a 20A Single Pole switch and for a 2' X 4' lay-in fluorescent light fixture. Attached is example for development of a assembly cost for a duplex receptacle.
