How To Go From 480V To 240V
How To Go From 480V To 240V. Go with the 480v system. In order to yield 208v this tap setting would be insufficient.
You simply need a appropriately sized 480v to 240v transformer (or 480 to 120/240 if you need a neutral). 480/240 transformers are a fairly common item and may work out cheaper than redoing everything else, especially if you'd have to change out some motors. We have our inventory stocked nationwide for fast delivery.
A 15Hp 480V Drive Will Be Easy To Find For Under 100$ And Can Be Fed From A Single Phase Transformer.
If you are in a situation where you have a shop full of 120v and 240v single phase machinery and need to power one big 480v 3 ph. This transformer would be connected between any two of the 480v lines. You also need to be sure that all the panels and wiring are rated for 480v.
If The Codes Require A Maximum Usage Of 70 Percent Of The Transformer's Capacity, Multiply 40 Times 1.43.
I need to derive 240v single and 3phase power from it, as well as 120v power. There are lots of parts that will be needed besides the transfomer. So, finger safe and fused sounds like a plan, so you'll need the accessories that go along with the transformer too.
Smaller Conductor Sizes, Easier To Work With, Cheaper To Install, Easy To Modify.
No matter how you wire this feed, you're going to get 480v phase to phase. The new location for our makerspace has 480v 3ph power available. So you would have to get a transformer to step up your 240v to 480v single phase.
Go With The 480V System.
In general, yes, the breakers will need to be downsized by about half. 480/240 transformers are a fairly common item and may work out cheaper than redoing everything else, especially if you'd have to change out some motors. We were going to set a 112.5kva 240v delta primary/480v y secondary transformer to take care of this new equipment.

To get 240v, we measured one of the phases and neutral, which gives exactly 240v rms as we want, however this goes against my research online that it should be 277v rms. Most transformers above 1 kva are listed to.
