Low voltage outdoor lighting transformers are subject to inrush problems when installed within a few feet of a breaker panel. This is especially true of toroidal types.
I understand that using a dedicated high magnetic breaker (HM or HOM) will prevent nuisance tripping at the panel.
My question is about the primary breaker located in some of the larger toroidal type transformers. It's common that inrush can trip either the panel breaker or the primary breaker in the transformer.
Will an HOM panel breaker prevent the transformer's primary breaker from tripping? In other words, do you need inrush protection for both the transformer and the panel or will the panel protection suffice?
