Utility Costs 
Without preventive maintenance, the electrical distribution system itself can waste $1,000 to $4,000 in electrical utility cost. Source: Infrared Research Inc.
Electrical Connections
"Improperly torqued connections and bad contacts cause increased amperage draw and power loss as well as heating and arcing (which is both ineffective and dangerous)." Source: National Energy Management Institute
Electrical connections can be deformed by over-tightening. This will also cause increased amp draw, power loss and heating. Source: Maintenance Technology Magazine.
Power Factor
Building owners and managers have installed power factor correction systems to avoid penalty charges from the utility company. Many power factor correction systems over 5 years old are not working as designed, if working at all.
An annual electrical preventive maintenance program will significantly reduce these energy wastes.
Motors
5% Voltage Imbalance = > 125% Power Consumption
An annual electrical preventive maintenance program will significantly reduce these energy wastes.
