I have a large patch of brambles to clear on my new plot and a kind friend has given me a 2200watt bosch shredder for the task.Sadly on my allotment there is no power so my question is what size generator should I buy(hire)to cope with the power load,I cannot work out the watts/kva equations so would welcome advice from people who have much more experience than me !Many grateful thanks in advance,Nick

hi nick, go to your locall tool hire company they will keep you right.any gen putting out 2.5 k should solve your probs.all the best peter.

2200W is 2.2KW...So Like Peterf says you will need smthing that puts out more than 2.2kw they are normally quoted at a peak and a sustained output so you want 2.5kw sustained. With Bramles I would cut them down with a cythe and burn the cuttings.

While you are at it, if you get a generator to the job the ordinary electric hedge cutter will help slash the tops off. Get the green leather gardening gloves that are readily available. If you have the patience you can clear it all with a good pair of secateurs, cut in short lengths. I am blessed with a cordless mini-chainsaw which they call a lopper, much faster and will cut through the thick stuff at ground level, they are still available but pricey. If you can't get the roots out e.g. with a mattock wait until growth restarts and spray with brushwood killer or glyphosate until you are sure they are dead.
I must agree that the bonfire seems a more sensible means of disposal.

Watts = KVa only if the power factor is 1.
You could end up being a slave to generators, oil changes and pistony thingies, rather than allotmenting.
Slash and burn has my vote as well

I (the current measured in amperes) x V (volts) = power (measured in Watts) I x V = P and by transposition the current (I) = the power (W) divided by the voltage V. and to bore millions the final one the voltage V = the power (W) divided by the current (I). Hence IV=W. Ivy Watts a very nice girl.
1000 watts = 1 K.watt.....what, what dont ya know.

But you need to factor in AC vs DC and the PD drop over the length of the cable taking in account the thickness of the cable(Ohm)and the ambient heat qualirty of the insulation.
Oh its like being back at school. Now as we are in science where is that biology book with the line drawing of a nude lady.
