This is an updated version of the first arrangement. Because the electrical code as of the 2011 NEC update requires a neutral wire in most new switch boxes, a 3-wire cable runs between the light and switch. The red and black are used for hot and the white neutral wire at the switch box allows for powering a remote controlled switch.
The source in this circuit is at the first switch and the light fixture is located between SW1 and SW2. Three-wire cable runs between each switch and the light fixture. The hot source wire is connected to the common terminal on SW1. The common terminal on SW2 is connected to the hot terminal on the light. The traveler wires are spliced at the fixture box to run between the traveler terminals on the switches.
This wiring diagram is used for 50 and 60 amp circuits. The receptacle should be wired to a dedicated 50 or 60 amp circuit breaker using 6 awg cable. The 50 amp circuit is required for new installations of some large appliances requiring 240 volts. Two wires carrying 120 volts each can be combined to provide high voltage to heating circuits and one of the 120 volt wires can serve lights or other low voltage circuits in the appliance.
This diagram illustrates wiring for a 4 way circuit with the electrical source at the light fixture and the switches coming after. Two-wire cable is run from the light to SW1 and 3-wire cable runs between all the switches. The hot source is spliced through to the common terminal on SW2 and the hot terminal on the light fixture is connected to the common on SW1. The travelers run from SW1 to T1 on the 4 way and from T2 to the travelers on SW2. Note that the white wire is wrapped with black electrical tape when it is used for hot in these circuits.
