Pringle Switches
Pringle Switches
(OP)
Should I have any concerns about exercising a 2000 amp main Pringle switch that hasnt been exercised in about 10 years?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Pringle Switches
Otherwise, I'd try to get as much load current off it as possible before opening.
Seriously, if there is any way to kill the incoming power before opening/closing, I'd strongly recommend it.

"This switch will provide years of trouble free service in the closed position"
If at possible de-energize the feed so you can deal with it in a safe manner should it malfunction.
We get called in to "stand by" many times a year when customers are required to operate bolted pressure switches after a long dormant period. Problems run about 50-50.
Older non stored energy (no springs) switches can be tricky depending on amperage. An older 4000A switch may require 2 men and a boy to close properly.
Be safe.
