the new am2

[sean123]

hi, i have just done my am2, which is the new version. i was never given a lot of information before hand so i will list done the equipment you have to install, this might help some people who dont know what to expect or never had any decent information given, like my self.

s plan heating system with solar sustainable energy element. basically a solar panel which controls a cylinder and has a sensor which is supposed to be on roof. 2 port valves, sensors for solar panels and boiler allready have pre wired flexes. the joint box is like a push in connector and u use feral crimps to terminate. all the information is the just follow the drawing. really quite easy.

3 phase motor - just supply in from board to pre wired dol starter and take the suplly out to the motor from starter in sy flex. so dont worry about control circuit because its allready there.

cat 5 - just one cat 5 from one out let and the other end goes to another outlet.

smoke alarm - fp from board to unswitched fuse spur then out on to tray ( use fp clips not cable ties) and to a carbon monoxide detector. thats it for that.

lighting - 2 way and intermediate with 1 light only in pvc/pvc.

ring - few sockets with one socket spuring of to another socket.

main bond to incoming gas and water.

6mm swa to a isolator which then feeds a 3 phase commando socket.

and thats it really.

they chuck in different size breakers in the box so that u have to think on which breaker to use, allthough u get give a db chart.

i hope this might help people who are about to take the new am2, so that you know what to expect.

How did you go about testing the Insulation Resistance on the motor circuit and central heating?

 

[whazza22]

Do they tell you the maximum demand for test sheet, and do they tell you if its TN-S or TN-CS?

 

[Benn]

Do they tell you the maximum demand for test sheet, and do they tell you if its TN-S or TN-CS?

They have a enclosure which says what systrem it is, mines TN-C-S.

Is the SY flex a straight run?

What size is the armour?

Am I right in saying that there isnt actually a motor, its just a starter to a box (acting as a motor)?

Have you got a sketch of what they bays look like?

SY from DOL starter to motor.

6mm armoured

My motor is a metal clad enclosure with a pic of a motor on front but with some plugs type of thing so possibly a motor could be plugged in.

 

[whazza22]

Ideal! Thanks mate.

Did you have to work out max. demand?

How did you go about testing insulation resistance on central heating?

 

[sean123]

you just test to the point of isolation. which is the switched fuse spur, u dont test the heating circuit itself

 

[whazza22]

Thanks.

Do you have to clip the central heating cables or are all the cables for components enclosed?

 

[sean123]

enclosed

 

[whazza22]

How long did it take you to wire and connect all the central heating?

 

[sean123]

just over an hour

 

[whazza22]

Really?- is that to wire and connect all flexs, programmer, spur etc? (i got two and half hours to do it)

Do all cables in programmer need to be labelled?

 

[sean123]

half of it is pre wired. no dont have to label it

 

[sean123]

you should have a specification which tells you what you need to do on it?

 

[whazza22]

Yeah I have a spec, just never done it before and really worried that I will run out of time especially as one guy took 2 and half hours to wire it.

 

[sean123]

i never done one either till am2. try not to rush it tho, be quick but dont rush. u can easily get some stats or whatever muddled up. well lookin back on it now it probably did take me hour and a half, what are the other bits u have to do

 

[whazza22]

Just have to connect the data points in but they are both wired, put 2 neutrals in a connector block for the swa, and put in 2 fly leads from the p-nuts.

All of the above plus the whole central heating (apart from supply to the spur which is done)

Think 2 and half hours is enough?
