Will this work for 1/0 aluminum??

I find when stripping URD or overhead triplex/quadplex I have to use the 2/O for 1/O, 3/O for 2/O, 4/O for 3/O, and the 250mcm for 4/O. This is due to the thickness of the insulation. Something to note is you'll want to score where you want to stop stripping since it's hollow and can pass-through the other side.

Can you buy and change the end pieces that determine what wire size it strips?

Yes there is blades you can buy and also change the location to what you prefer. They can go up to 750 MCM

Will this tool stripe large metric conductor cable from abroad for example 240mm?

I can't give you an accurate answer. Think of this as a large mechanical pencil sharpener. If you use the correct size wire in the corresponding hole it will strip...like a pencil sharpener would sharpener a pencil. Also think how you spiral peal a potato or orange. All that said...you can take, say a slightly smaller gauge wire and strip it in a larger diameter gauge hole but there will be some manipulation of the wire needed to strip it correctly. This thing is awesome and wish I'd of had it 20 years ago. My arthritis in my hands might not be so bad.

Will this work on actual Cable for the Cable company?

It won’t do a multi conductor cable like a 901 or 401 cable but anything similar to thhn or xxhw’s jacket thickness it’ll work. It’s not gonna work on any medium or high voltage wire with a semi con in it

Working for Potelco on PSE property. The 350 UG wire does not fit in the 350 stripper. Probably works fine for other wire brands. Just wanted to try it out. Can’t leave a bad review if I wasn’t able to use the product. Wanted others to be aware when ordering.
