ask me questions, see if i can find in appropiate time, no trick ones please only if you have nothing better to do..

isit 622..

Try 134.2.2

 

[Sparky Ninja]

Actually it's either, alltough I believe the exam wants the answer as the designer.

BS 7671 does.

 

[i=p/u]

im officially head scratching at annoyance with a complicated book but great guys if its what i want

you were winding me up willder about 20 degrees on zs... bet you scitter when younger,,,,

Oi I'm still young (ish)

Zs reference was valid, but shouldn't be a concern for you with a 2382-10 exam. It's more of a 2391 question. I can explain further if you like, if you have the OSG it will be simple to explain.

BS 7671 does.

Yes BS7671 states that the designer should recommend the interval for when the first PIR should take place.
Then GN3 states, that the inspector carrying out the initial verification should recommend when the first PIR will be required.
Nice to see such co-ordination between the publications.

minimum height of a socket for a rewire?

I think it would be wiser to advise the right information in this thread though, don't you?

I believe I have provided the right information?

1) BS7617 is a non-statutory document, but if it is adhered to, compliance with which statutory document is likely to be achieved?
2) When may non-rechargeable auxiliary batteries be used in caravans?
3) With a DC voltage of 125V between conductors how would the installation be classified?
4) What is the most likely cause of an overload current arising in an electric motor circuit?
5) Under what conditions is the design current of a circuit defined?
6) Name a type of lighting equipment likely to require additional protection against thermal effects?
7) A component of a support system consisting of regularly spaced elements which mechanically retain a cable is defined as?
8) Name 3 SELV sources that will provide combined basic and fault protection?
9) A protective device giving protection to both overload and short circuit must be capable of breaking current up to what level?
10) A 230V single-phase heating circuit has a design current of 25A. The length of the PVC insulated cable is 20m. The 4mm[SUP]2[/SUP] cable installed has a volt-drop of 11mV/A/m. The voltage drop under full load conditions is? And does this comply with BS7671?

There isn't one in the BS 7671

 

[telectrix]

kV not kv............

isn't it kU now?

 

[clicon357]

isn't it kU now?

In the same way then that its no longer P=IV. As the OP clearly knows!

 

[i=p/u]

450mm to top of socket, but can keep same as was... so only new builds at 450mm????
