    Have I possibly damaged the underfloor heating mat?

    Your readings sound perfect, you want a mega high reading to earth, generally tie l+n together and test L+n to e but for an element it won't matter L to n on insulation test will test zero as it's such a high scale v. low resistance.

    UK High PSCC and strange readings - help much appreciated

    Yes the megger 17xx defaulting to low current every time is annoying. Low current is good for nowt more than making observations IMO. Also while on test leads, my Megger was acting up on continuity tests on multiple lead sets, a gentle tap with the pliers on the inserted test lead plug stops...

    24 module DB to include 16 MCBs

    If going rcbo (and I'd echo not wanting that many mcbs on a RCD) Hagar do an 18 usable way that already has SPD onboard, ie 22 module. And they're my current favourite.

    UK High PSCC and strange readings - help much appreciated

    Re: using the service fuse as backup is acceptable , I queried it for a 10k scenario with the niceic tech line a few years ago. But 20k, wowsers! Don't have an old backup machine lying around, borrow one etc?

    Appliances in bathroom cupboard

    A cupboard in a bathroom is still in a bathroom. Silly restriction IMO as in all of the world it seems its only the British who can't be trusted with sockets in bathrooms but that's how it is, as said switch spurs/flex outlets or whatevs. Main downside is when Currys turn up with a replacement...

    Faulty fan replacement responsibility?

    As said no way that's come from the fan. Assuming vent-through-wall - there's not a long duct attached for condensate to form? These can be aggro. You didn't say the fan had stopped working either? TBH if the clients first instinct is to stamp their feet and demand paint rectification then...

    Working by yourself

    ^this. I discovered recently I'm officially nuerodiverse. What we used to just call being an awkward ****. But Ive allways liked to do things my way and be in control of all elements. Sometimes I'll get a grunt to do some chasing if I've got lots on but mostly I don't care for having to...

    Social housing unsafe

    Twas ever thus. Every LA I've dealt with has always managed the remarkable combination of being unbelievably fussy and demanding over standards while managing to hold the worst going. Did one a couple of years ago, sheltered housing so you think they'd try to get it right, built in the 80s...

    NIECEIC or Napit reg.

    That's all well and good, but my comments regarded the capacity of those carrying out EICRs to reference technical documents and understand British specific systems, I did not mention foreigners or their English skills, although as you've brought it up I'd suggest you leave the office and visit...

    Automatic gyroscope laser level

    Another +1 for the huepar here, have a 3x360, seems to be the brand of the moment. Essential for plotting level sockets when the screed is yet to be poured, and lots of incidental "because I have it" uses... Straight downlight lines and the other day I was fitting modular lights with those...

    UK Thermal Imaging Query

    I have a topdon tc001... Don't know how it ranks against the more upmarket kit but a useful little tool to impress the clients, above is the neutral block of a service head of a flat with flickery lights. Ironically the council had just employed I think a lumberjack to fit a fireproof enclosure...

    NIECEIC or Napit reg.

    Ain't that the truth; what exists in the way of training today seems to be focussed on sites/new build, simple skills like fishing a cable or being delicate with flooring are vanishing. As for the background knowledge for testing, I asked my nic inspector how, when inspecting+ testing was...

    What's the most badly designed accessory you've had to install?

    If there really is a heaven and a hell and in particular a purgatory I pray every lighting designer spends theirs fitting their own creations. "Seemed fine when it was sat on a workbench with two hands to work, less so hanging off a stepladder and trying to support the thing. Top tip...

    DB In Bathroom

    Put one in a zone 2 before.. niceic advice line were happy with it! Assuming extractor fans are in use, can you place a vent to external/other space in the electrics enclosure, effectively giving it slight positive pressure?

    individual RCBOs or a main breaker RCBO? and what trip level 10mA or 30mA

    Sort of; technically speaking the 10mA is required to hit the 40mS target at 50-149mA, whereas the 30mA device can be happily snoozing along for it's 300mS alarm call. Of course in reality they tend to all meet the 40mS time whatever the fault current. 10mA pointless for general use though, a...

    Consumer unit MCB selection

    I wouldn't bother with a con unit for this, just leave it as a 16a (or 20a) radial and feed the lights off a switch fused spur. Con unit would add nothing unless you were looking to seperate the lighting provision for safety reasons.

    SSE 3-Phase Upgrade Gone Wrong!

    When I was on the electric board We had a pair of pillocks connect a housing estate to a very large genset, the n lead was in two parts and not connected which they didn't realise, which had the effect of giving everyone 400v and borked VCR. Not something one should laugh about but the two...
