AM2 starting tomorrow

[philaxgt500]

hey all,
So i've got my am2 tomorrow and feeling a little ill with worry right now, I'm rubbish at fault finding so can someone give me some advice please. like...
1. what tester to use for a short and what could cause it,
2..what reading i would expect from a short?
and the same question with an open circuit and again with a crossed circuit,
I hope some one can make sense out of this.
cheers phil

also if anyone has any question about the am2 let me know as i have a pre am2 book here with me ;-)

Hi Phil

Im in the same boat as you

Due to book my AM2 shortly but very worried about pretty much everything including fault finding lol

What information is in the booklet as it may be handy for me?

Thanks

 

[philaxgt500]

i know its such a horrible feeling right now, and what makes it worse is if i fail a section i have to pay for a retest myself (at the moment the college has paid for the test)

so in the booklet there is
safe isloation procedures....
steel wired armoured walk through with earthing nut a the lockring (it has grub screws in it to hold the earthing cable on)

how to wire the two way and intermediate switch with the wago connections

how to make off sy cable in to the motor circuit

how to do data cables

f.p 200 cable

boiler system with 2 channel timer, room therostat, boiler, central heating pump, hot water valve, centrol heating valve solar pump and solar controller

cable segregation

bonding

electrical testing and inspection

and a little bit on faultfinding

Are you allowed to take the booklet into the AM2 test and refer to it?

Also can you take your own notes and information in with you?

Thanks

no

i did the old style am2 few months ago

dont worry about the fualt finding its easy all i had was a continuity tester fualts are easy i managed find all the fualts with plenty of time to spare

remember
open circuit
cross connection (connected wrong)
short circuit

some are very easy to spot like no speed controller in the fan controls or wrong fuse size

No, but your aloud to take as many smoke breaks as you like, ( i don't even smoke)
you can't take your own notes, but you have got paper in there so if you just remember it and as soon as you get in there just write it all down quick.

To be honest i done my wiring today as it was must better then i thought, Went so much easier then i had expected,
I've got fault finding along with the 1hr multiple guess tomorrow. I've got to get 70% in the multiple guess which has got question on absolutely everything even part p.

 

[whazza22]

Dam! haha

How bad is the central heating system?

Would you say its easier or harder than the older AM2?

 

[philaxgt500]

Central heating system was easy, its pretty much dot to dot. i'm not joking either.
Ii would say easier as you only have to 2nd fix, but saying that i never really looked at what was involved in the old am2

i struggled on fault finding today, but the on-line exam wasn't as bad as i had expected.

I've only got testing to do tomorrow then its all done, just have to wait on my result

 

[philaxgt500]

evening all,

i've got my testing tomorrow and i've got to use the old style testers,

which i have been told are better but i have never used them.
Does anyone know anywhere on-line that explains how to carry a full test with these set of testers.
Also how do i test the rcd with one??
cheers phil

Hi

I use on of these testers at work

You can't do an RCD test with this one, but you can get the Zs reading. However, some of those Robin testers will trip the RCD when doing a Zs reading. They should provide you with an RCD tester so you can measure the disconnection times.

Thanks sounds good, to do the zs reading do i just take out the earthing conductor and test between the live and neutral incomming? and it is the same reading for pfc??

perfect just what i needed,

 

[whazza22]

To test the Ze - Main switch OFF, Disconnect the main earthing conductor and test between the main earthing conductor, incoming neutral and incoming phase. Record reading.

There are two parts to Test PFC :

1: Place the neutral and earth lead onto the Neutral and the phase lead onto phase. (PSSC)

2. Neutral lead on neutral, phase lead on phase and earth lead on earth (with main earth reconnected) (PEFC)

Record highest reading from the 2 (PFC)

Make sure you change the dial to PFC on tester.

Also remember to reconnect bonding before taking pfc reading.
