I don't know if those surge strips even do filtering anyway. When the house was built, the electrician put the exterior lights on the living room circuit instead of pulling a separate circuit.Īnyway, due to the way the wires are run (all in exterior wall cavities - packed with insulation and not easy to access from below or above), I cannot easily run a new circuit to the area behind my entertainment center, nor can I get a new feed to the exterior light switch box, so I am faced with only one option - noise filtering.ĭoes anyone know of a (relatively inexpensive) product that I could plug in between my living-room UPS and the receptacle it is plugged into? I tried putting an APC SurgeArrest in-line, but there was no change. After some investigation, I discovered that the UPS only buzzed when plugged into line power and only when the exterior lights were turned on (a string of 27-watt compact fluorescent bulbs on an electronic time switch). Anyway, the living room SUA1500 began emitting a very loud buzz a few hours after I plugged it in and plugged my loads into it. I have had the first SUA1500 in my network/server rack in my basement for a couple of years now. I recently installed another SUA1500 in my living room to sit between my entertainment center and the incoming AC power. This was originally posted on APC forums on
Commonly referred to as " Hocks Noise Breakers", these custom fit devices are made with medical grade high-strength silicone material.
