I need to install a buck boost transformer on a natural gas filling station (no prior experience with these transformers). The supply voltage of the equipment is listed 208/240 volts 1 phase. The unit draws about 8 amps at full load. It has an electronic control board and a compressor. The supply voltage dips to 197 volts under load and shows 207 volts with no load. The transformer I have ordered will boost the voltage by 10%. This will put the voltage without load at +/-228 volts. If it wasn't for the dual voltage ratings on the nameplate I would have been leary due to being so far over 208 volts without load and what it might due to the electronic board. By the way this equipment is about 400 feet from the source with #12 wire. Obviously the wire size should have been larger from new (I didn't install it). I am only using this transformer as a short term solution and will look at the bigger picture because I can see more problems arising in the future in this corner of the building. Anything else I should be concerned about.
