Electrical - Self Assessment Survey
A great deal can go wrong if an electrical distribution system is not adequately maintained. As electrical loads cycle between high and low demand, thermal expansion and contraction cause connections to loosen. Electrical panels that are never cleaned accumulate dust and dirt that deposit on these connections. The loose and dirty connections provide a high resistance path that are directly responsible for electrical failures.
Electrical preventive maintenance (EPM) is cost-effective in several different ways. First, it is cheaper to make repairs to equipment before it fails. When electrical equipment fails, particularly protective devices like circuit breakers or relays, there is usually subsequent damage to other components in the system. In addition, an effective EPM program will improve equipment efficiency and reduce utility bills. A loose or dirty connection has increased resistance which results in higher power losses. By simply cleaning and tightening electrical connections, you can lower these energy costs.
