someone help me on this please I carnt work it out

[leon92]

what is meant by the term "basic protection" In relationship to electric shock ? a) contact with parts or conductors that are live under fault conditions. b) contact with parts or conductors that are not intended to be live unless there is a fault. c) contact with parts or conductors that are not intended to be live. d) contact with parts or conductors that are intended to be live. Be very helpfull if you give reason for the answer thankyou ?

 

[i=p/u]

basic protection = protection against electric shock under fault free conditions, this is the defination , now match up

 

[SirKit Breaker]

Basic protection is what keeps you safe in normal use. A good example, a plastic light switch. Its construction means that you can touch it without getting a shock. Basic protection is usually provided by barriers or enclosures, there are other methods.

Leon,

Can I ask why you ask, curiosity, are you in training, or is it something you cant get your head around? It is always a good idea to mention it when you ask basic questions. There is nothing wrong with asking the basics, but there are some in here who take great delight in having a go. because they think the forum is only for "experts".

Cheers.............Howard

I am in training and I'm sure its b) tell me if I'm wrong ? Thankyou

 

[Richard Burns]

Not B, you have three choices left!
From I=P/Us post:
If basic protection is prevention of electric shock in fault free conditions will the answer be contact with parts that are only live in case of a fault?
From Sirkits post:
If there is a plastic light switch that is protecting us from getting a shock, if there always a fault when you turn a light on?

 

[brman]

Is that the full wording of the question? If it is then it is a typical C&G cr&p question!

Basic protection isn't contact with anything. As i=p/u says it is protection against shock in fault free conditions.

If the wording of each option started "prevention of contact with...." then the question makes more sense and you might need to review your answer ......

Scrounge yourself a copy of the 17th edition, the old red one will do, and look it up in Definitions. It will be good practice for you.

Cheers...........Howard

 

[leon92]

Are I its c) then?

 

[brman]

Are I its c) then?

No.
Think of it in terms of the definition. "protection against shock in fault free conditions"

Now consider that an obvious form of basic protection is an enclosure or some form of insulation.

Is that enclosure or insulation intended to....
a) prevent contact with parts or conductors that are live under fault conditions.
b) prevent contact with parts or conductors that are not intended to be live unless there is a fault.
c) prevent contact with parts or conductors that are not intended to be live.
d) prevent contact with parts or conductors that are intended to be live.
?

A big clue here is in the definition. "fault free conditions"

the 2330 gets a lot more complicated than basic protection,

 

[i=p/u]

its one of many questions to understand

 

[leon92]

I carnt get ma head round them and there is the same answers for fault protection which it is totally baffleing me now !!!!

 

[i=p/u]

so there's no fault , and your protected from live parts

 

[brman]

To be honest, if the hints given so far don't help then you are best to go back to your tutor and get him to explain basic/fault protection to you again. Much easier to do this in person than on a forum!

 

[i=p/u]

yeah i can remember doing me head in, cause i just wanted to know it all . but i didnt mind asking a zillion questions and holding him back.. so much that he use to chat louder as i had words at end of me tounge and them just looking to get out but didnt want to be rude.. crazy

 

[brman]

Tutors job is to teach you - make him work for his money

 

[Pavtekno]

I think you will find your answer is (D) ie: protection against touching live conductors, as in a junction box, switch unit etc:

 

[D80]

I would have said don't point out the answer but at this stage there was a 50/50 chance of getting it right.

Basic Protection (Direct Contact in 16th edition money) is simply that - protection from a part that IS meant to be live. Terminals on the back of a light switch, busbar in a CU etc. If you can poke a finger in and get a shock off them then basic protection isn't met.

To the OP, what do you think is meant by the term Fault Protection?
