Due to my hobby , I have probably changed wheels over a thousand times but when putting my winters on I managed to hurt my foot standing on the wheelbrace and ended up in hospital, could not walk or work. I am sure wheelnuts have got tighter as I have got older. Quite frankly I think many people...

To convert VA to A , I generally divide by 700, although if using Tony's line voltage at 433 it would be 750. So 25MVA gives a fault current of 33.33KA. You can get MCCBs at that level, I think Merlins would be 36KA standard, however although I have measured PSSC higher than 25KA with on site...

25MVA looks wrong, it is rather high even if the tx is onsite. The tx has an impedance which drags down the maximum fault current, If you have a look at it, it may tell you on the rating plate. He's probably right at 25kva and its probable that your 15K breaker could be outside its limits when...

yes , they are getting rid of class2 and rolling into one, apparently if you make more than 16K profit you are worse off. Plumbers have no chance... ha ha

Paa, Vauxhalls were always an average car at best......Kia's are better, it would be better to build Kia's in the UK.

Actually TB coming out so strong is just playing into the hands of Brexit, his credibility is toast.

where there's a will there's a way. Good luck for future. My business model is very different, I have a small set of clients and cover more than electrical. my website is pants but I don't advertise and as such its only there as a marker. I still think the best business is repeat. For this you...

My parents are 80+ and use internet banking, internet shopping and dad loves his Galaxy Tab. Neither had a job that involved using computers, so if they can, anyone can. Sounds like cant cook wont cook to me. GOV should crack on and get it done asap. DVLA stuff is really good but the PAYE is...

Large corporations already have to deal with quarterlies and an overall annual, I think most of the allowances are annually based. Dividend allowances are annual, so is personal tax allowance and personal tax thresholds which will need some thought about how and when to pay oneself.

A bit like VAT but what worries me is how you manage it when your personal tax is still annual, I see lots of corrections needing to be made throughout the year. In 6 years only had to correct a VAT submission once but cannot see me getting CT correct so will probably just stuff in an estimate...

Was testing a mixer, brand new Chinese motor, was around 35kw, L1 0.7, L2 1.5, L3 1.6A on no load, as soon as I got 25% load on, the amps soon converged, although L1 never overtook the others. I was testing because the users were stalling the drive, so I was helping get the right volume of...

Assuming square wave output ? - then its just a question of getting very accurate timers. Again assume you need to alter the frequency, then what you need to think of first is the total range of frequencies that need to be set. e.g. if you want to set a frequency from 0 hz to 100hz to five...

If you can get at both ends of the windings you could always to a continuity to see if they are similar there, but I would be more concerned with imbalance on a loaded motor when there's some proper slip.

Doesn't work that way, gilts are traded, if China wants out, its bad for the remaining investors but the Gov have their money already, as for the power station no idea what happens if China change their mind or don't make a payment date, I guess the gov will have to step in and raise premium...

My understand is that the power station is being built by the French, the Chinese are simply financing it. Basically because china has such an excess of cash from exports, they need to invest it. Gilts are so low around the world that something like a nice power station will give them a higher...

assume the 3kw elements are heaters ? So whats on L1, L2 and L3 of the loads. i.e. 3kW element and PSU, 3KW element and 0.75KW heater etc etc Neutral is not usually a problem unless the loads are harmonic generators (like lighting)

What are the loads, how are they controlled ?

Eaton?

exactly my point, you would need the equivalent of a current domestic ticket and EGA in calibration, it narrows the odds somewhat... lol

True, but you still need to be competent, generally this means having the same training and relevant test equipment to correctly carry out the work. In reality, I am GSR for commercial installations but I wont service my own boiler as I have not had the training that my domestic engineers have...
