Will hopefully tomorrow get the multimeter ( Homepro should have one ?) and with a lot of guidance from yourselves I will investigate the earth issue. HomePro should have cheap digital meters and ABB branded RCDs, they look like this, note the "Test" button. Make sure you get one rated at 63A (50A at a push).

BEVUP Posted July 29, 2017 Share Posted July 29, 2017 13 hours ago, Andrew Dwyer said: Yeah sorry if I made it confusing, I did say at the start I have no electrical background and only started this thread because I hear of the horror stories and wanted to run some things by the more electrical minded folks of TV. I will be relying on local sparky for any electrical work and as I'm new to the area will have to ask around the neighbourhood. Each AC and the water pump has a dedicated breaker next to each unit, the water pump is wired into the outlet circuit, the feed for the AC's comes from up above so not sure if it's lighting or outlet. Didn't see this last paragraph before - Looks like your Air Cons are hard wired into roof cabling hence the CU beside them just like the Water Pump (the Air Con guys do it all the time ) I only had one down stairs that had the cable already there but most probably twisted amongst other things in the roof & the 2 up stairs are just twisted into the roof cabling with no external CU (as it would be running back to one in the mains box ) Link to comment Share on other sites More sharing options...

Worry not, moving house is the single most stressful thing in ones life, I don't intend doing it again. The electrics are not dangerous per-sé just need improvement.

Andrew Dwyer Posted July 30, 2017 Author Share Posted July 30, 2017 Am gonna need a sparky to fit another couple of outlets so I'll shop around to find someone recommended locally and get him to fit the RCD ( 2800 baht !!, I know I know you can't put a price on safety ), change the underrated black cables. I'll also get him to try and explain the grounding situation to me and if any doubts " I'll be back ". In the meantime, thanks for all the help.

wayned Posted July 30, 2017 Share Posted July 30, 2017 Wow, 2800 baht! I just bought this on from Aliexpress for about 250 baht, din rail mount:https://www.aliexpress.com/item/DZ47LE-2P-63A-230V-50HZ-60HZ-Residual-current-Circuit-breaker-with-over-current-protection-RCBO/1738523017.html?spm=a2g0s.9042311.0.0.iDtOAB Link to comment Share on other sites More sharing options...

Hmmm, does seem a little over the top, but I don't recall what we paid for our ABB units, they're about 30 quid plus VAT in the UK. I worry about the small output terminals on those Tomzn units, how big a cable will they accept? (minimum 10mm2 for 63A breaker) Link to comment Share on other sites More sharing options...
wayned Posted July 30, 2017 Share Posted July 30, 2017 I have one in the shop. I just went out and tried 10mm2 VCT and it fits fine. I imagine that 12mm2 would also fit, but anything over that would be a problem. Link to comment Share on other sites More sharing options...
