Does anybody have idea where I can get any information about the use of a generator in the form of a cctv system on a towable lighting tower (modified from those that you see by roadworks)
Having questions asked by site managers saying that can only have 110v on site
The generator produce 240v within not available externally

You need to be careful as most site do not allow Diesel or Petrol on site, This is something you will have to discuss with the Project Manager/Site Manager

Who says taht you can only have 1!0V on site, and why, is it "their" rules, are they quoting standards, or regulations, or what?
Pray tell, because I KNOW what the law says, and I would love to know why they are quoting this at you.

Site requirement? Lots of places have restrcitions similar to that.

Its also down to what insurance cover they have taken out, If the insurance states no Petrol or Diesel On site, then there no way you can overcome this if you want the Job on site, Electical power is usally by means of 110v site transformer

I can see no issues with using diesel or petrol generators on site as often it can be the only means of providing power. Many items of mobile plant such as lighting towers, mewps, compressors, etc. have both 110v & 240v outlets, however the majority of construction sites manage their electrical hazards by insisting that only 110v tools are used, and often complement this by encouraging the use of battery/gas operated tools to reduce the amount of trailing cables. Obviously the use of such equipment must be appropriately managed taking into consideration positioning for refuelling, maintenance and fumes, who will have access, is a permit system required, etc. etc.
Many of the big contractors are very good at imposing restrictions on subbies without providing help or guidance on how to complete the job safely.

It is interesting thread, as we have seemed to have gone backwards in time on Electricity (Energy Source). In early 2000, main contractors used to restrict dual voltage generators and insist on 110v. Anything over 110v had to be agreed and the appropriate control measures in place to prevent release of the energy source. Although reading some of the comments here, it seems some are not aware that the Main Contractors are not imposing these rules they are requirements, as the Electricity System used is Temporary and not Permanent.
Construction is deemed as Adverse or Hazardous Environment Regulation 6. So, the initial planning stage to establish the Electricity Scheme used on site, using the Hierarchy of Controls would introduce the best system in place to prevent exposure to the potential hazard to the workforce, rather than just individuals.
HSE issued guidance on Electricity Safety on Construction Sites HS(G)141(formerly G24) 1995, is a very good document clearly states “give priority to controls which will protect all workers rather than a number of individuals. For example, a reduced low voltage, site distribution system such as one which is 110v centre tapped to earth (110v CTE), will ensure that if distribution cables are damaged the risk of fatal shock to anyone in the vicinity is virtually eliminated” Going back to the original question on the modified Lighting Unit (Mobile), undertake a risk assessment for the use of the unit and discuss with the HSE Department of the Site Manager. There are times when a higher voltage has to be used on construction sites i.e. welding, commissioning stage / Testing etc. Main Contractors do allow larger units / voltage on site as long as the control measures are in place to mitigate exposure of the hazard.

even using 110v power you will need a higher voltage source at somepoint, there is no problem using any voltage on a site providing it's assessed, welding plants are 415v commissioning uses HV power etc, generators are hugely common on buildng sites to provide temporary power.
Hamsters on wheels don't really cut it these days.

Are we all assuming that the site is outdoors ? Maybe it's in a unit and the fumes are the problem. Ask if you could use a generator with a particulate filter if it's sited indoors, or use outside of the unit with long leads.

I still fail to understand the issue. More info needed.
There is no statute law reqirement preventing diesel, or petrol generators, nor 230V, nor 400V on construction sites. If companies are doing this then they should be justifying their actions with a robust risk assessment. Just "because we say so" is rubbish, and one of the reasons H&S has such a bad reputation.
