Generators without central tap

[alec mercer]

hello,

i am desperatly after some help, so thank you in advance.

i am looking for a generator to power a feed auger of 18m in small mobile sheds. there would be 3 sheds wired together but with a delay, and one central plug to which the generator would be attached. this would then power the sheds.

i need a 16amp generator and it needs to have 240v. i was under the impression that a 240v and 110v generator woudl bemore than sufficient. however subsequently our electrician has said that due to a center tap on many of these machines the RCD would disconnect if there was a fault. sunsequently putting the building at risk of going live.

they have then said that i need to look for a straight 240v single phase machine, or a 450v machine.

the issue i am havign is: are they correct? where can i get this type of generator as i do have somerequirments for it:

1) it needs to be smallish and lightish (i.e. size of a wheelbarrow and 100kg), this is because it will be taken around fields every day on the frnt of a tractor.
2) it also needs to be robust and capable of been taken around fields.
3) clearly looking for something reasonably priced and ideally a diesel.

thank you for your help.

Alec

Hi,

When you mention RCD, is this integral to the machine or are you looking to put one on the live side of the load? I don't see where you would get the tripping problem from, as this would be a standard set up. Don't forget you will need to rod the machine and test frequently as you are going to be moving it around,

Regards.
