anyway...when i use the mutlimeter to test with all the pumps off..i registered a reading...and after that, every pump i on, the reading increases a little ..but when i on the chiller, the reading decreases
so how to tell what the problem is?

my dad then use a test pen to place at the ground plug of the chiller and on every equipment...only when the UV is on then the test pen lights up..but after offing the test pen...still trip...then off the pump for the chiller, still trip...

any one can help?

did you switch off the UV?
