I have a friend who is an electrician coming over tomorrow. He has some experience with wiring isolation transformers. But I need to be able to tell what I want. So, if I am understanding this correctly, some are suggesting wiring this as 240v in 240v out even though it will be on a 120v circuit to help keep it cool. Is this correct? Will this work? It seems consenus that if I have it wired balanced, it will half the kva rating. If I do that, will .9 kva be enough to run the digital part of my system (Apple TV, Monarchy DIP, Tube Audio Designs TADAC Tube Pre/DAC, AV Switcher, and perhaps a Tivo)?
Wiring an Isolation Transformer
I found a pristine, never been used, Topaz (Square D Company) 91018-31 1.8 KVA Ultra Isolator Line Noise Suppressor for $40. Other markings include .0005pF, 50/60 Hz, 120/240, Indoor Type 1, Enclosure Class 1-80 Insulation. However, it has no receptacle or chord.
My first question to the forum, is how to wire it? Could I just take a short extension cord, cut in half, wire the male end to the output side and the female end to the input side? Should I use bare wire under the screw terminals, or should I crimp/solder on spades? What wires go on what screw terminals? Some suggest balanced is the way to go. But some suggest this cuts the power in half, some suggest it doesn’t. Here is an example I found of balanced wiring:
Input:
Neutral (white) to H1
Hot (black) to H4
Ground to chassis
Output:
Hot 1 (white) to X1
Hot 2 (black) to X4
X2/X3 center tap connected to chassis ground and outlet ground.
Is this all there is to it? I am a complete newb when it comes to electrical work. Is this something I can do myself, or should I hire an electrician? Any assistance would be greatly appreciated.
