You say No - but seem to mean Yes. You are saying that a fuse is both certain to blow at less than 55A and yet may not blow at all between 25A and 55A - all in the 10s timeframe. Between 25A and 55A is definitely less than 55A, of that I am sure In the graph provided, it is only more than 55A at which the fuse is certain to blow within 10s.

Should not the 13a fuse shown blow (at the 10 second scale) on more, not less, than 55a?

Apologies if I was unclear. That's about it. It doesn't really contribute much by saying you can run a 150amp gadget via a nominal 5amp plug when there is a transformer involved. I don't know how much a welder draws via the mains but my 140amp welder has yet to break its 13amp (nominal) fuse

The welder will not draw 150A via that plug; it will have been transformed to a lower voltage.

It's not known as a plug tap for nothing..........

Which large accountancy practice has an average income per employee in excess of $2m per employee? Is it the one of the big four that your son works for? According to this https://www.statista.com/statistics, worldwide: Deloitte - £143k PWC - £146k EY - £143k KPMG - £129k

KPMG UK (for example) had a turnover of £2.3bn and 15,595 FTE employees year ending September 2020; that is just under £150k per employee. https://home.kpmg/uk/en/home/media/press-releases/2021/02/kpmg-uk-reports-2020-annual-results-and-outlines-further-plans-to-invest.html

Yes - so the T&Cs, in that respect at least do not breach legislation. Refusal to grant a licence unless you accept all the T&Cs may be a breach. What would be interesting is someone accepting the T&Cs, obtaining the licence and then withdrawing their agreement to any of the terms that were non-statutory.

I think you are looking at this the wrong way round. If CRT wishes to use its statutory powers to board a boat, it may well be required to give the required notice. But if CRT asks nicely to board my boat now - and I agree - there is surely no breach of legislation.

Does either of the first two breach legislation? If so, which enactments? If CRT pushes it luck in refusing to grant a licence unless you accept its T&Cs - it might well be out of order. But if I give CRT the right to board my boat without notice, I can't see legislation is breached any more than if I gave you the same right.

For motor vehicles, s148 of the Road Traffic Act provides: Avoidance of certain exceptions to policies... . (1) Where a policy is issued for the purposes of this Part of this Act, so much of the policy as purports to restrict— (a) the insurance of the persons insured by the policy, by reference to any of the matters mentioned in subsection (2) below shall, as respects such liabilities as are required to be covered by a policy under section 145 of this Act, be of no effect. (2)Those matters are— …..(b) the condition of the vehicle, https://www.legislation.gov.uk/ukpga/1988/52/section/148 So, bald tyres do not mean no cover. Which is pretty logical as little point in compulsory insurance if it is easily voided by the actions or inactions of the insured. The insurance company might (I think) lay a separate claim against the insured, RTA and bald tyres have little to do with boats

The real money is in not finding any

Correct, of course. But it is not, as previously advanced. the shuffling of boats that makes a hereditament composite. It is the combined domestic and non-domestic use - which is another matter. If you shuffle residential boats then (probably) the hereditament is enlarged from a single mooring to a multiple mooring - with likely savings in Council tax due to the banding system. But no savings (in very broad terms) for business rates via shuffling. If you mix domestic and non-domestic moorings by shuffling leisure and liveaboard boat, a composite hereditament will be created resulting in a liability for both Council tax and business rates. The financial consequences will depend on numbers and values - but most probably the total tax will increase - again as a consequence of the banding system. You would most likely pay less tax if all the moorings within a hereditament are liveaboard than if the two types are mixed
