Installation of a generator for a house.

Tomgunn
Hello all,


I'm moving house, (been here for over 42 years'!!), and one of the first items on my mind is installing an electrical generator.


SO; I guess there will be contactors / switch gear etc as I would like it to be 'automatic', (OR, maybe 'manual' too), changing from incoming to the generator.


a; What would be the best type of generator to purchase? Load wise? I'm not too worried as the bigger the load the bigger the           generator would need to be as long as I could run the basics within the house.


b; What switch gear would be appropriate?


I would't fancy the idea of switching tails around on a Henley block each time I needed the generator to be in use!!


Thanks, in advance!


regards... Tom

    I don't think you will find a sheer pin on a 5kVA unit either Mike. It would be nearly the size of a dressmaker's pin, and that would be particularly unreliable. a 10HP diesel might have a torque of 50NM available on a good day (5kgF @ 1m radius) including the stored energy in any moving parts. The sheer pin on a 40kVA unit is only about 3mm dia in the shaft. They are quite difficult to break even with a short circuit fault!
