Get power cuts where I live, purchased a 5KW GENERATOR, have heard if I switch OFF mains IN and plug GENERATOR into a plug in the house, I can light up the house.

yip, nope & yip.
very dangerous if some one forgets to put the main power back on before you take the generator off.Or forgets to switch the mains in off in the first place! and power cut over.....Oh dear.
you can get a spark to put in a switch that will cut off house power and only let the generator work.
it's a sort of three position switch
house on, off, generator on thing
i hope this helps
Bakerman, my guess is that the sparks and subsequent flames will light your house up a treat.
Give it a try and let us know!!
Seriously though, my guess is that it will be highly dangerous.

sorry DON`T understand
If I switch mains OFF its O.K then turn GENERATOR on and THEN I must Switch GENERATOR OFF, the switch mains on after power cut over ?

Re: Re: Re: Lighting up my house
the dangerous thing is the both voltages going in together to your house.
the generator would be fine on it's own pluged into your house, but if when the power cut happened you forgot to switch off the mains supply in when the power cut was over you would have both national grid and your generator pumping 240 volts into your whole house.....
BANG is the term to describe what happens next.
it still never really ok running your house this way, you should get a spark to set it up for it.

Yep - that's right.
What you should buy - if you haven't bought yet is a voltage sensing generator that AUTOMATICALLY trips in and out with the mains power.
That way you never have to think = great !
We used to use 2 HONDA ones for the pit wall for the Races.
Very critical !!

Could I also point out that you cannot feed 5kW through a 13-amp socket without risking damage to the ring main and distribution unit.

As well as the dangers mentioned by m'learned friends above ..
You'd also have a live plug. Not a live socket but a live three pronged plug coming out of your generator.
If you (or more likely someone who didn't know, or maybe a child) unplugged it while the generator was running and touched the plug (something we normally might do because plugs are usually only live when plugged in) then it could be a nasty shock, burns or even a call to the undertaker.

You need an 80amp switch between your Power co supply and your consumer unit. Get it wired in before the Meter or you will be metered on the power you generate. You will need to pull the main fuse into the house before fitting the switch and will need the permission of your power co to do this. I did this cause I have an overhead power supply which is a bit intermittant at times. You need a switch which can cope with the power in from the mains 80/100amp the other side of the switch has a feed which I can plug into my 2kw generator. Runs the lights TV and central heating and the kettle or microwave.....but not both

You need to get an automatic change-over switch. What this does is sense when you have lost your mains supply and changes over to your generator supply. Depending on what kind of generator you have, you can get this switch to automatically start your generator for you.
Similarily, when running on the generator supply, and the mains supply then returns, it can (if properly configured) change back over to mains and can switch off your generator.
A switch like this guarantees that you do not parallel the mains and the generator supplies. This is the most basic requirement you will need.
You could go and synchronise both supplies to do a smooth transition from generator back to mains if you wish but this is silly money for not much benefit (in the case of a domestic supply)

Bakerman, sounds as if you need to contact a local electrician. Let your fingers do the walking big man! Safe is good, not sure is seriously stupid. Get a spark in for advice - never mind the costs, think on what you might loose.
