new db in garage upgrade bonding needed?

[WayneL]

I apologize for my late reply but some of us have work to do rather than sitting on a forum all day. I thankyou greatly for your advice and opinions. I have another problem now, the customer doesn't wish to have a cable secured direct to the surface of her house which has recently been decorated. Can i just state there is no bonding present in the deviations section of the cert. will mr niceic take this as acceptable??

No you can't - and wha's it got to do with the NICEIC??

Should you be doing this job if you have to ask these questions - if the 'bonding' needs doing, then do it.....what's the problem??

You sound like your looking for permission, from us, not to do it.

Because the Niceic are our governing body???? I am looking for advice from you , much more experienced, guys to solve this problem in the hope you may have come across it before. I know I should upgrade the bonding but have an issue with what the client will allow me to do. Yes it needs doing but how can I if they won't let me. And considering my installation has nothing to do with the rest of the house where the pipework is I'm trying to find out how necessary it is anyway. I mainly undertake new rewires so additions are an area where I occasionally need some extra advice what's wrong with that? Thought that's what this forum is for...

God knows how I've been getting by for the last 5 years then because I've never had one thing to do with NIC.

Even though they are just bonded together it doesn't actually go back to the met? My knowledge of 16th regs are limited is this how it used to be done?

This is basic stuff, but I'll tell you anyway.

The installation that you intend 'extending', (with your garage supply), will be protected by ADS and 'Main Protective Bonding'.

As your new sub-main to the garage will become part of that installation, these protective measures need to be in place and adequate.

ADS ensures disconnection of the supply, within a specified time, under single fault conditions.

Main Protective Bonding, (of incomming services), ensures that the 'potential difference' between 'Exposed Conductive Parts' and 'Extraneous Conductive Parts' is kept to a minimum.

Can you not see that an earth fault on your new 'installation' in the garage will result in a rise in 'voltage' on all 'earthed' metalwork within the whole installation, (including the rest of the house).

If the incomming services weren't bonded, and the fault wasn't cleared quickly enough, what do you think would happen to anyone who happened to be in contact with some earthed metalwork and a 'not-bonded' water pipe?

You need to tell your customer that it is required to be done as part of the job - or you can't provide a supply to the garage.

Hi mate as wayne says
If there is no Main protective bonding present and jsut the cross bonding then needs doing before you carry out additions and alterations to the existing
No Bonding No likey and neither will the assessor lol
