Terrible work connected to my install.

[ajbelec]

Hi All,

This is my first post here, i've found this forum very helpful, so I'm hoping for some advice from those of you who may have been in my situation.

I have rewired a large house, including a sub main with 3 way board on the end of it for an air source heating system.

The problem I have is this - the 'defined scope' installer who has carried out the electrical work for the heating system has lashed it in.

For instance - SWA simply inserted into the board through 20mm knock out - no gland, the other end is in a PVC compression gland steel wire exposed. Therefore no earthing to armour.

No identification of cables, no isolator for boiler or immersion - oh and no labels on the board.

I don't really want to put this right myself, as it has been paid for already.

I haven't mentioned this situation to the client yet, I think I will first call the installer and 'ask when they intend to finish'.

Is it worth calling their governing body and asking them about it or am I just on a hiding to nothing?

I don't want this cr*p work on my job!!

All opinions welcomed.

Thanks,

Andy.

your 2nd sparks is correct. the more rods , the lower the Ra and hence the fault current will be higher and the protective device will break quicker.

not only that, but if the house rod is old and corrodes or the termination fails, you've still got an earth on the installation you've installed.

I have probably missed a point somewhere along the line, but I have been reading this post secretly whilst my missus is talking at me. I definitely remember being taught that you only have to earth the armouring at one end, and ever since this is how I have done my installations (obviously I wouldnt do it like this if I was using the armour as a C.P.C). My understanding is that you are only earthing the armour, (much the same as bonding a pipe, you dont have to bond both ends). So if for any reason someone stuck, say, a spade through some armoured cable, and touched an inner core the circuit would trip. I dont see any reason why you would have to earth both ends, but one thing is for certain it has nothing to do with parallel paths. Like i said though, I havent really read the post thouroughly, so I might of missed the point. If that is the case, sorry for being thick
