if I, say, clamp a 120V AC lamp cord, will it measure amps correctly? What about a 220V pool pump motor? Thanks!

No. You have to use a AC line splitter tool found here on amazon. The line splitter plugs into the wall and then the lamp plugs into the line splitter. Then you can use your clamp meter to measure amps. this separates the neutral and the hot wire so you can meassure the amperage.

The clamp is not that accurate. I think its good for testing starters, alternators, etc. I just don't think it would it would work for trying to see less then an amps worth of difference. I wouldn't bother using it to measure anything less then 10 amps.

As long as you can attach the tubes shown to a different pump, it should be fine. We have already upgraded our pump, so the pump can be changed out to a pump that does 220v, as long as the tubes running to the pool can attach to the pump. (I am not sure of the diameter, but fittings could be bought at a hardware store if needed.)

I have the 3 hp motor. It runs on 220 volts and utilizes a 30amp plug. My electrician installed 20 amp breakers and I have had no problems. Unfortunately, there is nothing in the manual that covers this.

Michael, I'm sorry that I can't answer your question. I do know that it works great with 120vac.

It will measure to .001a/AC-DC but will not calculate amp hours. Milli amps yes.

What you mean is "How many amps does it need to start the compressor?" Ours is plugged into an ordinary 15amp house hold circuit and doesn't trip any circuit breakers, although the lamp on the same circuit flickers each time it cranks on.

This is only a 30amp extension cord. They do make one that you are looking for which is a 50amp. You should probably buy a "dogbone" of 30 amp and one that is adaptable to a 120V outlet. The 30amp is for campgrounds that don't have 50amp services and the 120V is so you can plug it in to your house if need be if you're not wired for 240V. Hope this helped.

It uses what is kind of know as split 240v 120 per leg. I do believe it would power your pump if your pump can be plugged in like it was a dryer plug.Hope this helps. Dan Rooks

Well this product has an adjustable voltage setting, but it's not rated to regulate amperage. ..How sensitive is the equipment you are using? It should work just fine..The only reason I say that with reservation, is that i dont know what you are using it for,and i wouldn't use it for say a breathing machine.i usually just use it to test my item's that i am selling, then decide whether or not to go find or fix the neccessary part of the item. Absolutely though, this is a good product, and should meet your needs

That depends on what voltage the pump is running at. It could handle 40 amp at 110, but it would require pulling 110 off each leg of the 220. If it draws 40 at 220 it will pop the breaker all the time on start up. You've got a pretty big pump if the latter is the case and you should probably go to a diesel genset.

One think I failed to mention, the PTAC is 220 volt. It is on a 30 amp breaker. That has a potential to be 6.6 KVA by itself. This is worst case, but I suspect it pulls at least half that. You might want to do the math on your heat pump, but I suspect it is too much.

As long as it is 110/115 volts, (thats a regular three prong plug) and the amperage rating is 15 or less.There should be a plate on the motor with that information and the volts on a list with a lot of other stuff like Hz. Check this. If your pump has the extra large round plug with flat prongs, thats a 220 or 240 volt and it will NOT work for that.

The input voltage is 120 volts AC. A lamp cord that plugs into any 120AC outlet will be ok. The output will be 12 volts.

This transformer actually boost voltage to 170v 120hz. I have tried quite a few low cost voltage transformers they all do this. So give it a try but make sure you could return it if it doesn't work. Your pump will run a bit warmer than at its rated 50hz.

To measure current that high you would need a clamp ammeter or I would recommend the fluke i200 clamp that works with this meter. Remember that if it's AC then there is no polarity. I am assuming that your campground is supplying 120 or 220VAC
