Tips for wiring multiple lights between three-way switches include carefully planning the wire path and fixture locations, conforming to the National Electric Code standards, observing safety measures, and consulting an expert if the project proves difficult or interferes with existing installations. A common approach is to wire the additional lights in parallel with the first, making sure to factor in the change in voltage consumption.
Careful planning helps in minimizing the budget, buying the right products, wiring correctly and maintaining the circuit. Some planning activities include understanding the existing wiring system, obtaining and examining relevant wiring diagrams, and obtaining the right tools and supplies.
Following the rules and guides in the National Electric Code ensures the wiring conforms to building and wiring codes. NEC regulations provide advice on wiring, including wire sizes, voltage and conduit sizing. Using multiple light fixtures in the circuit increases the voltage it needs to operate effectively. The existing wiring may be adequate to accommodate additional fixtures, but ascertaining that the circuit components are ideal for the new load makes the wiring more reliable.
Safety is an important consideration when dealing with electricity. For complicated cases, hiring a licensed electrician to perform the work minimizes the underlying risks. Factory pre-assembled cables are already color-coded and consistent with NEC, reducing the risk of injury or code violation. Using quality fixtures also improves the safety of the circuit.
