Abstract
A modular electrical wiring system (10) is shown including a hanger (12) and an electrical connection block (26) independently and adjustably held from the hanger (12) by four adjustment screws (106). The electrical connection block (26) is formed from three control boxes (28, 30, 32) and a receptacle box (34) which sandwiches bus bars (50) therebetween. Each bus bar (50) includes a connecting portion (56) located in one of three depressions (38-40) and which are accessible at different depths through slots (88, 90, 104) formed in the second, third, and receptacle boxes (30, 32, 34). The connecting straps (122) of electrical devices such as an outlet (110) or a switch (190) are sandwiched between a cover plate (182) and the receptacle box (34). The switch (190) includes bus bars (196, 198) having first ears (204, 220) sandwiched between the casings (192, 194) and second ears (206, 222) having the electrical contacts (212, 228), with the ears (204, 206, 220, 222) being bent from legs (202, 218) extending through slots (213, 230) in the casing (192). The outlet (110) includes a T-shaped ground conductor (118) having end portions (154) extending from the head (152) for slideable receipt on the outer faces of pedestals (158) located inside of a cavity (156) formed in the casing (112) and having a leg (150) also extending from the head (152) through a slot (162) formed in the casing (112).
