arc fault tripping

New work, bedroom low voltage halogen bulbs 4 fixtures with transformers. they trip 15 amp breaker.
Wired properly. No I didn.t run nuetral to ground. Any ideas appreciated thanks tool

Double-check all connections to verify they are tight. Are the low-voltage ps passive or active devices (i.e., heavy transformers, or electronic devices)? Disconnect one fixture/transformer at a time and see if that helps isolate the problem. You could also have a nail or staple in a wire somewhere. Does it trip immediately, or intermittently after some arbitrary delay? Not all arc detecting cb are created equal...some have better filters in them to prevent nuisance tripping.

will check thanks

Here's what is strange. these two bedrooms had new incandescent light fixtures earlier, no tripping then. As soon as we switched to low voltage with transformers,both rooms[ 2 seperate arc fault circuits]
started the occasional false tripping . We are licensed for this and did a new 200 amp service,all new wiring signed off. We all are the Manuf. Guenne pigs for these arc faults,i feel
