    I need some help here!

    I run the plant in a Hospital. We have a new facility with a 150kw electric boiler that has no condensate return as it supplies sterilizers. Here is my problem. The boiler requires a major blowdown daily. The mfg instructions say to disconnect the power and my boss interperets this to mean throwing the main disconnect. We have told him that the disconnect is not designed to be used in that manner and he is going to create a problem over time. The boiler has a on/off switch that will accomplish the same thing and he refuses to believe us. What say you? Thanks, Ken

    I was taught disconnects and circuit breakers weren't meant to be used as on/off switches.

    But, he's the boss.

    i service a place the uses the 3 pole breaker in the main panel to start and stop thier air compressor, have had to replace it 3 times in the last year, too cheap to buy a disconnect switch, but dont mind forking over the money for a expensive breaker each time, breakers are not meant to be used as on/off switches

    Serviced a place the maintenance crew was using the diconnect to cycle a pump. The thing got so worn out it would miss a "knife" from time to time and single phase the pump. The H.O.A. switch for the mag starter was already worn out. What did they do??? After two pump motors ( 7-1/2 horse) now "we just use the wooden paint stiring stick sitting next to the disconnect to jam the blades in to make sure we dont burn up the motor" Dont worry bout the disconnect, hoa switch or the ddc s/s problem!!! Don't use the disconnect. Use the system switch
