As a rule of thumb, most EHU supplies are 6 amp. This is normally enough as long as you don't plug the kettle in at the same time as the heaters.

A 750w generator will be half of this, so you could run the heaters on gas, and be ok with most other things from the genny

I have a 2.2kw genny.

It makes a lot of enemies on some sites.

But it made a lot of friends on the night we had a power cut.

Use them sensibly and you shouldn't have any problems.

Also worth remembering is that generators are inherantly unsafe as they are not earthed. .

A generator does not produce a voltage with respect to earth, unlike mains electricity where the earth and neutral are tied together so I am afraid you are scaremongering without fact.

Anyone earthing a generator should seek professional aedvice before doing so as it can cause serious risk if not done properly. In fact users of generators should be very careful as "spike" suppressors are useless because the biggest number of problems are caused by voltage surges when an appliance is switched off and the engine speeds up creating very high voltages.

I am no expert on generators but did check with the manufacturers.

If you are using a generator let it run for a few minutes before using any appliances.  This allows the generator to settle down.  Also use a surge arrester at the generator.

Early days I started generator when attached to load.  Blew tv transformer and microwave. (Microwave was not in use, only connected)
