I have installed a switched outlet to control two strips of LED tape lights. The 180 watt transformer plugs in to this switched outlet. Three other outlets are also powered by the 20 amp circuit serving the transformer, however, no load has yet been plugged in to these outlets. I can plug my electric drill into any of these outlets including the outlet that is to serve the transformer. All work fine and the breaker doesn't throw when I run my drill. I can plug the transformer into an outlet on a different circuit via extension cord and the transformer works fine, tape lights come on and all is good. I have verified the transformer outlet is getting 120 volts using my voltage meter. The transformer 120/240 switch on the transformers circuit board is switched to 120. I am baffled as to why the breaker keeps throwing. Please help if you can.
