Have you seen the 203 papers on here Paul?
The 203 is the Hardest exam of the lot. If it's any consolation, I too failed the 203 the first time around.
I failed to do any revision for that, because I was spending too much time sorting this forum out. :_|
Good Luck In your re-sit.

right chaps i have now failed the exam 3 times and my time is running out.
im failing on the electrical principles,theory and operatiuon part. any help please
i remember theses question so will u answer them for me aswell thanks.
Q.an electrical relay which causes contacts to open or close is.?
Q.an overcurrent protective decice is one which relies for its operation on?
Q. purpose of a circuit breaker in a circuit is to provise protection against?
Q.earth fault current will flow in a 3 phase installaition if?
Q.which type of protective device can discrimate between short duration overlaods and high current ppath?
A. rcd
B.type b mcb
c. rewirable fuse
d. can not remember

also.
q.whats is the ration of standing ladders?
1/4
1/5
q. A transformer has a primary winding with 1100 turns and 380 secondary turns. It is connected to a 230v supply. What will the secondary voltage be?
how do you work this out?
and questions on power factor would help

my red
it is pure resistance.
no inductance or capacitance (or they cancel each other out)
if you can try and remeber the first 2 questions.... minds gone blank to what i correct questions could be

"Ratio" for putting ladders up 1:4 1/4
e.g.
If the top is 4m up a wall the bottom should be 1m out from the wall.
Transformers (rob ots in disguise oooppps sorry
Blushing)primary windings / seconday windings = primary voltage / secondary voltage
i.e.
1100/380 = 230/secondary voltage
2.894 = 230/sec'volt
sec'volts = 230/2.894 = 79.47volts.

a-RCD the red herring option
I guess they mean c the rewireable. short duration overload?
as b-MCB would trip probably
or it could be d????? :^O
Q.which type of protective device can discrimate between short duration overlaods and high current ppath?
A. rcd
B.type b mcb
c. rewirable fuse
d. can not remember
the answer is B, a MCB can discriminate between short duration overload (inrush of current), and overload if correctly rated.

sure? i would imagine the 'short duration overload' in the question is something like a motor. in which case, a fuse would hold up better than a type B, which could trip before motor has got to speed
ah didnt read the type B part there. should read things better many apologies
a rewireable fuse has no inrush current rating and would not discriminate, unlike a Mrated BS88, or a type c or type d breaker
there is no correct answer here. I feel this maybe a question that has not been copied on to this forum correctly???? or is that just me

it could be that answer D is BS88.... in the original post he couldnt remeber D
