Like any electrical/mechanical piece of equipment, transfer switches should be serviced on a regular basis. Cleaning and lubricating is essential for proper operation of the emergency power system, just like the generator set itself.
EEP offers custom service plans to suit your requirements. Maintenance can be performed when you are doing annual shutdowns or regular servicing of the emergency generator system.
When you perform regular service, reliability and longevity are greatly improved; it's a good investment.
