Need urgent advice please help.

Just to add a bit more context, if a top-notch, fully qualified electrician makes a simple 3-wire connection, it would still be expected that the connection - especially the earth - was verified in some way (even if that's only a simple multimeter test from some exposed part on the hot tub to some earthing point on the isolator/ or the main installation).

Everyone's human and it's all too easy to make mistakes - whether it's the terminal screw biting down on the insulation rather than the copper, or wires being placed into the wrong terminals because the manufacturer has altered the design and this one has a different layout from all the previous ones or a stray strand of wire that couldn't be seen in the failing light. Qualified electrician's aren't expected to be infallible, so it doesn't seem sensible to expect someone else to be.

The answer to that is a crystal clear 'it all rather depends' .

If the fixed wiring at the site was tested before you got there maybe that makes it OK - so do you or the customer for example get to see the test result sheet from the installer ? If not then some kind of subset of the full tests may be  in order.

If the pool was tested before it got there ? So is there something rather like a PAT certificate ?- I do appreciate its not 'portable' but the same tests  ' is the insulation resistance good, is the earthing conductor unbroken' should still be verified by somebody, maybe you, maybe your warehouse, maybe back at the factory 

If so then no  need to check that.
If both are true, then maybe you don't need to do much other than give the wires a reasonable test tug and a quick look over for the right colours on the right terminals and good metal to metal contact before you tighten the cable grips  and put the covers back on. - assuming the terminal outlay  is easily inspected visually if not then a meter check is better.

If no to any of the above, then how else is that risk mitigated ?

1. Hi Chris, yes this is exactly the case. This is as far as the electricians work goes, then I am made to wire the tub in using the armoured cable tail left, and turn the tub on without testing it

If the boss/duty holder does not supply the installer with a GS38 compliant tester (for proving dead well actually NOT LIVE AT TIME OF TEST) or allow them to purchase it and claims expenses then that is a sign for further discussions.  The same hold true for a set of VDE screw drivers and cutters.  Yes we are told to work dead but sometime things happen and VDE is an extra layer of defence/barrier

If cable entry into the rotary isolator is not from the underside/bottom with appropriate outdoor glanding then that is a sign for further discussions.

Thus you may not need to be an electrician to fit the hot tub but you need suitable instruction by a qualified and competent person.

Sidenote.  All connection made outside/outdoors in the UK should be from underside/bottom.  If top entry is used then with time and weather moisture ingress will occur into the enclosure.  Some people call this external influences, other say it is workmanship issue.

Worth looking up a GS38 compliant tester.  Something like

Another thing to look up is

Once you have the above info and parts you need to be trained or instructed by a qualified and competent person.

The cables always run from the bottom, but as mentioned we do not have any testers, and never have done, nor does an electrician come back to test the tub themselves. From what I've read, when wiring a tub you must legally do initial tests (dead tests and live tests.) before the tub is comissioned and handed to customer. Not one has been tested, can you please verify what I'm saying is true or is it just waffle from Google?

Thank you 

I am staggered!

How do kitchen fitters cope? They must have to wire in cookers, etc.

I would say that wiring an appliance is within the competence of a reasonably careful householder. However, glanding and making off armoured cable is a completely different matter.

I am not surprised that you wish to be anonymous. I would reassure you that if you are an employee, your employer has responsibility for whatever you do (provided that you have not deliberately ignored instructions), so if anything goes wrong, the company is sued rather than you.

Does anybody else fancy a C1 for this arrangement?

The H&S guidance I pointed to would apply to anyone fitting or repairing domestic appliances.

I wouldn't expect the hot tub itself to be tested against BS7671 as it's an appliance and will have a completely separate European harmonised standard.

But the connection to it would be?
