Feeling Disconnected?

摘要

Regardless of size and type, disconnect switches are typically shown as the same, nondescript symbol. If you don't find out and know everything you can about the disconnect switches you are estimating, you could be losing your company thousands of dollars and even a bid here and there. The most commonly seen disconnects come in staged amperage sizes of 30, 60,100, 200 and 400 amps. There also are 600-, 800- and 1,200-amp sizes, but these are very large and are usually found on the power one-line diagram.
