See the attached image. I have been sent to a building that is about 15 years old. It has recent had its Communal consumer unit changed and since then the communal Lights have been having issues with tripping the RCD. It is a shared RCD but for testing I have disconnected all conductrs of other...

Time for me to purchase a sparkly new MFT. Never actually owned one, always used works (no longer work there). I'm after some opinions. I don't have a load of cash atm, I know with testers you generally get what you pay for and if you ask 10 sparkies what is best, you will get 10 different...

Good day to one and all. WARNING: probably a bit of a boring story here. I'm in a bit of a pickle and trying to find a way out without hindering the rest of the family in much way. I have technically been made redundant on Tuesday gone with immediate effect. It's rather complicated affair but...

Can somebody just confirm that the rotor on a brushed portable genny should have continuity when tested at the slip rings? It's just a winding isn't it? Head is a little fried and no power coming out this bloody thing. It's testing open circuit so thinking it's knackered. With the avr...

Good day to all. Is there anything against a Consumer Unit going in a wall unit in the kitchen on a new build. It falls within the Part M '1350mm to 1450mm to breakers' rule. One of the bods has queried a ruling about it being above a worktop. I can't remember seeing anything about that...

Car Charging points: I've not really dealt with them to be honest but have some drawings for new builds and designer wants a 13a single socket outlet installing outside for car charging. From what I see this will allow for mode 1 or 2 charging. No problem. New build so supplies are TNC-S...

So, what are the options for Alarm Door Contacts on modern uPVC or Composite doors? I personally don't think it would do either style door any good drilling the frame channel section or the door itself to flush mount. What's the norm. This is on new build btw. Cheers

Is anyone NSI Approved? We are looking to become Silver approved but can't really make end nor tail of what it required. I'm thinking @Lurch is the man for this one, but all are welcome to join in ;)

Is it OK to fit a PV system sourced by the client and MCS certify it. Can't say I have ever come into the situation until now. If it is OK, how do you 'paper trail' it for QMS? Obviously no component purchases to log. Cheers

No, this is isn't related to my last post. Well I guess it is related in the fact both are regarding IR tests, but I haven't blown anything up doing IR tests, lol. If doing an IR test and are unsure if anything it left connected. Is doing a 250 V (L-N) to CPC test safe, even for 'sensitive'...

Here is what I currently see as a strange situation. Though I am hoping that with the responses of a few brain boxes, it will be cleared up. Was doing some testing today and went to IR test a circuit (Upstairs Sockets). I had disconnected everything and even checked that there wasn't a booster...

Let me paint a picture.... An industrial estate with 10 - 15 small units of similar construction. Single storey, brick and block build with trapezoidal sheet roofs that round off front and back to give a top hat effect raising the roofline higher that brick courses. Roof sheets supported by...

So, to setup and program XFP addressable Fire Panels you have to use laptop, physically connect and the right software. the panel manual states you need a XFP507. A quick google about brings up things like Link Now, you look at the description and it includes a lead and some software. OK, if...

New year, new tools needed. Been thinking about getting a torque driver for a while, had a look on ISSWWW and saw the Armeg 5 piece set and thought that would be ideal. Just the right price bracket for me. Then I looked at the review on the forum...

Merry Christmas boys and girls. Hope you all enjoy the festivities. Try not to get all stressed out with it. And a Healthy and Wealthy New Year for 2017 too!!!

My first Poll

When fitting a PV system with SolarEdge optimisers, how are you supposed to do the string tests??? Once the string is 'built' the optimisers only kick out 1V per module so no way to take the Voc and Isc readings?

Something has been playing on my mind today. Doing a little galv conduit job, something I don't get to do very often so the knowledge sometimes escapes me and I have to have a little revision time. On the job I was trying to show a couplle of the lads how to do it properly without just...
