I have a unique situation. I have a home built in 1955 that uses low voltage electricity (with relays, etc). I recently returned from out of town to find that none of the lights work from the switchplate on the wall. All outlets work fine and the 220 electricity is also fine. I have checked my fuses with a volt meter and all is well there also. There is a relay box in the attic and that doesn't appear to have a problem either.
Any light or other appliance that is plugged into an outlet is fine. It is just the touchplate lights that do not work....throughout the entire house. I have had an electrician out, who verified that the fuse box is fine and the power to the house is intact.
The only other info I have is that Touchplate Lighting Controls is the manufacturer of the relay box up in the attic. I also have 2 UPS (uninterruptible power supply) units in the house that supply power to PCs and TV/DVR equipment. Those are now showing a building wiring fault.
Does anyone out there have any ideas??? Also, can anyone explain to me how low voltage electricity works and why it is so different than today's norm? I have tried to find some information online but have had no luck.
