I have recently built a small table top train layout for a Christmas display. I have had two transformers quit working on me. I have used the same outlet for these two transformers. I also have a 30 + year old transformer that works in this outlet, but is noisey and always has been noisey. I just purchased a multi meter and tested the outlet's output. It registered at 123 volts. This seems high to me for a household outlet. On the same breaker I have been powering my big screen TV, DVR, lights and computers and not had any othe problems. So, is there anything to worry about? Is there a way to reduce the voltage from this outlet so I don't damage my next transformer that is on its way to me in the mail? Thank you in advance.
