[QUOTE="ralphdans, post: 371816, member: 25021"] Hi , New to forum and could do with some advice. I recently was asked to temporarily isolate some external air con condensers to allow some roofing repairs to take place. On opening the board I found it had no ability to accept three phase MCBs and had been connected to three individual single phase MCBS (correctly configured) across the three phases. Recognising the danger behind this I have refused to reconnect the units and this was understood and agreed with the maintenance company in the building concerned. Temporary air con units have now been hired in to cool the areas concerned and a price submitted to change the pan assembly in the switch panel to accept triple pole breakers. My problem is that the FM company overseeing the building have got involved asking how the configuration breeches regulation and asking me to quote specifics. Though I think this is obvious I am not sure which regulation(s) it breeches. Any advice appreciated as this guy is a bit of a know all and is trying to blind me with science [/QUOTE]
