Porter Cable 7424 - Wiring For Uk?

I've just purchased a Porter Cable from Autopia and have a 110 transformer.



How do I change the plug to one suitable for my 110v transformer?



The transformer accepts 3 pin plugs with neutral, live and earth.



Only trouble is I have a black and white cable on the Porter Cable - is black live and white neutral?
 
Yes, Black = Live.



Someone has posted full instructions on the Megs (UK) forum.



Cheers,



WD :xyxthumbs

I found AudiDrivers post at the bottom useful. I bought a 110 socket from B&Q for £4 and chopped off the 2 pin cable on the PC. I then wired black to live and white to neutral - there is no earth cable. Then you are set to work with your 110v transformer - I bought mine from machine mart - 1500w for £70



Here is a link for wiring

Just took me all of 15 minutes to change the plug over, very easy.



Plugged it into the trannsformer and all is well.



Now I need some decent weather, where it does not rain, just as you are about to apply the wax :rolleyes:

Just a quick question. I'm in the same boat, and I need a transformer for my 7424. The PC does not say how many watts it consumes, only that it runs on 3.7 amps. So, how big a transformer should I buy? 500w? 100w? Somebody help me, please. I'm raring to use my PC!
 
Ohms Law:



Watts = Volts x Amps



So 3.7A x 115VAC = 425.5W or 426W



For the record 110/115/and 120 are one in the same thing.

Sorry to nitpick, but this is not Ohm's Law. Ohm's Law is V=IR.



Watts = Volts x Amps is the simplified form of electrical energy flow, i.e. power or the ability to do work.



Sorry! :nervous:

But the statement is correct, isn't it?



And I have some corollary questions: what difference is there between a transformer and an auto-voltage regulator (AVR)? Will using an AVR be good enough to use for my PC? Or must I stick with a transformer? Which is the more stable/more worthwhile of the two?

Yep! The equation is correct for calculating electrical power.



Not sure what a AVR is but the transformer would definately work.
 
These figures will be for no loading of the PC, at start up and in heavy use the power requirements will be slightly higher.

Yes it is Ohms Law which isn't only V=I*R.



Ohms Law is a mathematical formual by which if two values are known for a circuit then the third can be obtained. It's not limited to just voltage.



I spent two years getting a Associates in Electrical Engineering Tech and four more years getting a Bachelors in Telecommunications Engineering. I've done so many calculations based on ohms law and in so many variations that my head still spins.



You are however invited to mathematically prove to me why it's not.



A AVR is an Automatic Voltage Regulator. A Voltage Regulator is a device that keeps the Voltage and a set value used mainly to prevent surges or spikes from harming electrical equipment.



A Transformer (either step-up or step-down) is a device that will take a input voltage and either step it up or down as the name implies.
 
So, MorBid, will an AVR do for a PC, assuming that its wattage capacity is substantial? Or, must I go the transformer route? Which is the better instrument for the Porter-Cable?

Hmmm.... Might not be the most definitive but maybe you would like to look at the Ohm's Law defintion here.



As for the mathematical proof for Ohm's Law, I don't think anyone would be able to do that, since the law was formulated by Georg Ohm a long time ago based on his observations and empirical evidence on the behaviour of current and voltage difference on ohmic conductors.



I'm out.

What I stated were the definitions of the terms. The lines become blurred when purchasing a product because some products will do both. So I would have to know which one you were looking at.



I googled for a transformer in the U.K and came up with this which should work nicely.



Obviously you will have to do your own leg work to determine if that is a reputable company to buy from. That was the first one that popped up in my search. Undoubtly there are others in your neck of the woods as this 220V to 110V conversion thing has been going on for quite a awhile.



What I am saying is something that meets the same specs as that one will work for you and you won't have to chop off any plugs either.
