The summer hot weather affects the way electric functions in businesses and in homes.  Air conditioning systems work much harder in the heat increasing the power demand it takes for them to operate properly. PECO encounters similar problems with their distribution grids.  PECO states that demand for electricity in the Philadelphia region soars during extreme hot weather. The demand is sometimes so intense that it forces PECO to reduce voltage output for brief periods of time to provide some relief to their main grids. Most PECO customers do not notice any impact from the voltage reduction. But in some instances these voltage fluctuations and reductions can create problems to your electrical equipment. If the main electrical service of your business or home is close to or at capacity, a voltage fluctuation can create over heating or overloading. This condition can lead to a possible failure of your electrical system.  For all of your electrical needs contact your licensed electrical contractor Lauterborn Electric.
