ok first question for you esteemed sparks,the final setting of vigi units (merlin gerin) after obtaining pfc pscc ze hertz,voltage,and total connected load, and the use of 160amp rccd main circuit breakers controlling other mccbs.when setting 3 or more dials on these vigi units,what are the parameters if whole installation is protected by bs 88 gg fuses.for the setting of the settings on vigi units,in order to set discrimination for overload,and rccd nuisance tripping of the rccd.all the loads are balanced and within fuse /mccb parameters,
on the set up i have just tried to configure,it has an amber warning light on the first vigi,the other 2 vigis i can understand,I/0 i/r BUT,there is no leakage current detected,but after air conditioning team set up there ac units,the main rcccd vigi unit goes amber alarm,then shuts off main switch after 20 or so mins,the ac guys says there side of install is clear,and we say our side of install is clear,as such,we are left with a blame game,all clean earths are sorted,and the ac (air conditioniong team) have decided to raise the limits of the vigi units so that the alarm disappears,this to me is masking a problem,as such,i ask u here for any sensible pointers.thanks.
hmmmm,maybe shoulda posted in ask question area,oops moderator,my error.
