  • I have had the pleasure of working closely with Electro-Motion on my fire pumps and emergency generator. They correct problems on the spot and report on anything which may need to be corrected in the future, keeping equipment in top working order saves us all in emergency repairs and costly down time.

    Are You Getting TRUE Automatic Transfer Switch Maintenance?

    December 17, 2014

    Automatic Transfer Switch Maintenance may just be another line item on your service contract, but are you getting what you think you're getting? Some service companies just press the "test" button or visually inspect the switch and clean the exterior cabinet. But are they:

    • Isolating the switch from all live power sources so that the switch itself can be thoroughly inspected for carbon tracking, cracks, and corrosion?
    • Disassembling the switch all the way down to the contact level for cleaning, lubricating, and inspecting?
    • Checking all power and control connections for deterioration?
    • Re-torquing the switch according to manufacturer's specifications?

    If they're not, what they're selling you isn't really maintenance, and not something you should be satisfied with when it comes to an important piece of equipment like your transfer switch - especially if you want to adhere to National Fire Protection Association (NFPA 110) standards. This is the standard Electro-Motion uses when it comes to transfer switch maintenance, the end result of which is a transfer switch that is as good as new and can be relied upon to do its job in the event of a power disruption.
