18th ed Arc Fault Devices - £120 each!

[Gavin John Hyde]

Just watched this video on the GSH youtube channel
Crabtree have released there 2 module Arc Fault device, reckon they will be £120 each and needed on basically all non light circuits.
They dont say specifically but were 'hinting' as the video was likely made last week and would be interested if anybody has there 18th edition books already (mine come early this week) what it actually says.
I can see £120 per circuit adding quite a bit of money to the cost of a new CU.. will be a hard sell to the customer... hopefully the 6 month grace period means they will come down in price quite quickly.

We could all switch to solid state switches.

Well, Spinlondon, if you had continued you would have seen the strategically placed Greggs coffee cup which might have meant it was filmed in Glasgow...
Rubbish video anyway, so stilted, background noise, poorly edited, and oh yes, they are in the shops now, but he only "thinks" the price-point (what?) will be "about" £120...well, what bludi price are they???

Costing aside there is also the issue of nuisance tripping. This is quite an issue in the States where their Codes require the fitment of these devices with the exception of some areas. The problem being many appliances and circuit switching devices have inherent arcing taking place. So called nuisance tripping of rcd/rcbos can generally be resolved, wait until afds start joining the party.

apparently these devices in the video are smart!! can determine good arcing from bad such as motors, appliances etc from poorly terminated and arcing wires.

An AFDD will not detect an arc < 2.5A.

Well in the video the guy carefully hints at somethings... and talks about the boards being the 2 row versions, rather than one long one. given the firms sit on the panel, i would not be at all surprised if they are not demanding they stay in the final version of 18th as they will put £ signs above the real likelihood of risk/safety requirement -sledgehammer and walnut come to mind! these would basically add around £400-500 quid to a board change.... can see the customers face already...
Had I done it before Christmas 2018 I could have done it under the 17th and avoided these expensive things. but now its February 2019 I have to install them and charge you an extra £500!!!

Two questions Gavin 1.How come you have a copy I thought it wasn't published until today (1st July) & 2. I thought it was to the designed date not the installation date.

Dont have a copy... should have it within next 48 hours... as i pre ordered.. i am scared to go out incase i miss the courier!.... I will likely skip straight to the on site guide for the simple version then go back to the big book... there are copies floating around and likely many people on this forum have copies as those with right connections had them before the official release tomorrow. but were under orders not to divulge the contents! maybe at 1 minute pass midnight the forum will be awash with people uploading the mystery contents!

haha ... well will have to buy them at some point so bought a bundle to save the £££s. As soon as the dpd courier message arrives i will have it sent to a pick up point so the thieving scallies who moved in to my building on the ground floor dont have it away.

Mrs Wiggins won't like having to pay that.

 

[sparkdog]

Mr Crabtree seems pretty confident they will be used.
