Great site wished id joined years ago to be honest, as mentioned been out game for a while but trying to get back in it again, thanks mark ill be in touch Monday. wealth of knowledge on here no doubt, one big family

then as we've gone to TT off the back of the pme we just give our self a 0.2 sec disconnection time to meet lol

but for a property on a pme for outbuildings supply summer house etc etc we wouldn't need step voltage calcs would we. or be concerned about overlap when the rod was installed. 

simply bang it in carry out Ze "Ra" make sure under 200 ohms done.  no need to worry about being in another overlapped earth zone ????????? well surely they could mean the same, unless an extension on the house with 2nd db is extending and up the garden is exporting

Hi Guys Ok so DNO law says no no no on export of the pme earth. so mr customer wants a supply to garden buildings etc . so swa is used earth connected at supply end to protect the cable, insulated at other end so 100% guarantee no earth present, just a Line & Neutral feed. ok so install...

calling Monday Da Boss is back in town baby. oh I want a nice new meter to play with, lol

Called this morning given same price as listed on there Web site. But didn't speak to mark or Mike  held fire for now. 😭😭😭 is it just one national number

I see the acti9 are dp rcbo but could only see them in c type , looks like I've caused a right old debate and I've only just joined lol oh my dayz baby. Ha ha very good luv this place already. So what are we saying we would need a double pole rcbo on high integrity circuit for the circuit to...

the rcbo is single pole device on own, so what if that was replaced with an mcb on the normal side protected by the split load rcd as this would be then DP plus an upfront 100mA jobbie

I was understood to believe that 100mA are fitted to give time for the 30mA devices to operate on A TT system

so if the rcbo wasn't double pole were in fact leaving a neutral intact on the circuit. ????  but if a main s type were there double pole would it comply

not done TT so off top of my head,  earth rod is classed as unstable over 200 ohms or near 200 ohms and depending if it was wet day on test so by fitting a 30mA rcd that gives additional protection and allows us to abuse the Level up 1667 ohms 100mA Time delay units are 500 ohms due to touch...

hi and welcome newb welcoming a newb lol happy dayz

isn't it safer if TT systems have a time delayed unit at the front end, aswell as the 30mA protecting the circuit are we at 1 sec disconnection times,  then as we have both do we limit to 500ohms or still at 1667. ?????

Seen at a hot tub install on a tt system.  Already installed.  10mm swa straight from c/u off rcbo off a high integrity circuit c/u was a split load wylex jobbie.  Noticed no 100A 100ma s type main switch at front end. Just a 100A double pole switch off TT feed in. No local rod at tub. So all...

I'll be on da blower then in morning then. 

Hi & good evening, do I just call the national isswww number as for  Mike or mark.  Think I'll go 1654b depending on price.  I'll keep my old kewtech kt60 & 35 as backups

awaiting price no reply as yet, sent message earlier today

Hi Guys I'm in the market for a new test instrument, however I have noticed that on the normal auction sites there seems to be loads of megger 1730s etc for sale but you never seem to find fluke 16xx for sale as often. Have megger got it sorted now with the right firmware for the job as im...

Yeah think I ended up just under.  Slave labour. Lol cheers for welcome
