i=p/u said:
1= reg 114.1
Correct Reg, But which statutory document?
2= annex A the awnser lys but all i can say doesnt mention rechargable or not
Looking in the correct place, the answer is there in BRB.
3= part 2 defintions
Correct place, but what's the classification.
4= starting and stoping reg 552.1.1
Wrong.
5= part 2 definitions normal service
Correct.
6= luminaires marked D reg 422.3.2
Although not correct a good attempt, your thinking along the right lines, but I want a Reg associated with the specific thermal effects of luminaires, type of luminaire?
7= cable cleat part 2 definitions
Correct.
8= reg 414.2
Wrong Reg But close, Name 3 sources?
9= reg 432.1
Correct Reg, what current level?
10=
11x25x20/1000= 5.5v so complies
Correct.
but do i need todo anything for full load markie sparkie ... or anyone if you out there cheers markie sparkie you can mark now You already have the design current is the full load.

If you can answer questions like this, where you are given no clues, then you find the multiple choice of the exam child's play, easy peasy stuff.
Well done for a first attempt, Answers in green are correct, answers in orange are partly correct or a good attempt, Answers in red are wrong. Have another go.

I must admit that is a weird way to ask that question regarding an RCD, so try again i=p/u

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?
