- Who has the responsibility for Code interpretations? When are rules in the PEC mandatory and when are they advisory? What color-coding is required on multiwire branch circuits? What is the basis for figuring the general lighting loads in occupancies?It is often desirable in designing an electric wiring system to be able to control a single appliance from two or more locations, for example, to control a lighting fixture from both the top and bottom of a stairwell. In home wiring systems, this type of control is implemented with three-way and four-way switches. A three-way switch is a three-terminal, two-position switch, and a four-way switch is a fourterminal,two-position switch. The switches are shown schematically in P2.40(a), which illustrates a three-way switch, and 2.40(b), which illustrates a four-way switch. If the lamp (appliance) is to be controlled from more than twolocations, four-way switches are used in conjunction with twothree-way switches. One four-way switch is required for eachlocation in excess of two. Show how one four-way switch plus twothree-way switches can be connected between a and b in P2.40(c) to control the lamp from three locations. (Hint: The fourwayswitch is placed between the three-way switches.)Estimate the length of conduit to perform the next bends. EMT will be bend using a hand bender. Provide your answer in inches (just the number) using up to 2 decimals. The picture shows two panels connected by a back-to-back 23.5" stubs EMT 3/4" 6.25 ft P
