Is there any opinion regarding LS din rail circuit breakers from voltex, they have the orange toggle. I was called for wires that was melting and when I got there it was a couple and melted before it enters the conduit, this is probably due to over current, I don't know what else could cause it and the breakers never tripped. Are there fake LS din rail breakers out there and how would they be recognised as these were bought from an electrical wholeseller?
