  1. Hi All

    Can anyone tell me if it is safe to run 5x400w lights from 1 circuit

    thanks
     
  2. The rule of thumb is to only load a breaker up to 80% of its capacity. On a 15-amp service with 14/2 gauge wire one should only load it up to 12 Amps MAX. Since most lights will draw 1 amp per 100 watts a 15-amp breaker can handle one 1K light each
