I've noticed that a bundle of people are buying 110v vacs (me included).
You need to bear in mind if you're using 110v that currents will be much higher than 240v.
So, a 3,000W vac on 240v will draw 12.5A whereas the same power on 110v will draw 27A.
Bear that in mind when you're buying extension cables. For a 110v, you really need big, heavy-duty cables or you're heading for problems down the line. You'll have trouble buying 32A 110V cables greater in length than 14M, so you may need to make your own.

i have a 240 vac but am thinking of swapping to a 110 so will need to look in to the extention cable thing. any ideas on where the best place to buy the cable ??

Hi Vin
on fri I bought the 240v from tech clean, it is slightly bigger and more powerfull than the 110v it was also £70 cheaper!
Also had a trip to omnipole for a few hours while they custom made me 3 different atachments for the top of the pole to fit in the gutter. so my entire kit has had an upgrade in line for the mountains of gutter work we have booked in
I got a 45m heavy duty 13a cable reel, the vac has 10 meters of cable and our suction hose is 10m, so 65m in total, no need to lift the geny of the van at all in future, my back feels better already!

110v is for site work and standard in the building industry you use 110v extension lead which are yellow and can be brought from any good Tool or hire shop and is a lot safer than 230v,yes you do lose a bit of power but not enough to notice but I rather get a bolt off 110 than 230

Only problem I see with 110 is that you are tied to your generator I have a large nursing home with no vehicular access at the rear. I would have to buy an inverter to operate it.

sure ye can buy a tranny which is plugged into 240 but delivers 110 to machine

These guys seem to have it, along with connectors. I'm going for 4mm as the 2.5mm only handles 25amps max and it's too close for comfort.

I'm likely to have 50m of 4mm cable spare, so I'll be open to offers...

Problems:
1. They are very heavy.
2. Often there'll be something like this: "These transformers are rated for intermittent operation at their maximum listed power capability for a duty cycle of 25%. I.e. 5 minutes ON 15 minutes OFF. They may be used in a continuous operation mode at a rating of 50% of their maximum capability. E.g. a 3.3KVA unit may be operated continuously at 1.65KVA. Primarily for use when using portable electric tools on outdoor sites."

From what I can find out from google, the 110v supply on building sites is dual phase 2x55v so unless you cut both 55v cables the shock you'll get should only be 55v below the 70v considered fatal to most risk. Is the 110v produced by a genny the same 2x55v dual?
