I know building sites don`t allow 240v on site but what about everywhere else?
Has anyone been knocked back or had it stipulated that only 110v must be used e.g. a hospital or council owned nursing homes/properties etc.?

we allways use 110v on any site for gutter vac

but never been told other wise

Cheers for that info,in the light of current Health and Safety awareness i`m quite surprised to see most retailers offer 240v vacs and i`ve just come off the grippavac site where they are only offered in 240v.So purely for the domestic market then? Omnivac offer both i believe.
  I have the impression that it is unlikely when doing commercial gutter work though that anyone is likely to check how the vac is powered and a lead running from a van mounted generator would suggest all is in order.

240v pros:

Less voltage drop over cable (important when using longer cable runs)
Can use customer supply at a pinch

240v cons:

Sites might not let you use
240v will kill you.

110v pros:

Very hard to kill yourself (Max voltage between you and earth = 55v)
Site friendly

110v cons:

Higher current: You need VERY thick wiring to carry the required current - take professional advice or read my advice (gleaned from internet, so no guarantees) on thread at http://www.cleanitup.co.uk/smf/index.php?topic=112254.0 (I have 50M or so of 4mm 110v cable spare if anyone wants to buy it)

Hope that helps,

Generally in industrial applications 110v is the norm.
I work in the steel industry and officially 240v is not allowed on the shop floor however safety is a bit slack so there are loads of transformers about for 240v.
In hospitals etc I would expect it all to be 240v

It had never occurred to me that i would be rained off,i normally clean gutters on wet weather days!

Appreciate the replies.
