A customer phoned me up the other day saying there was a burning smell, and I was ready to call out; but then she phoned me about half an hour later and said it had gone. I left it at that, until she called today and said “the breaker had tripped and won’t turn on”Continue reading “That explains the smell…”

Arse!
A call at 4am resulted in me talking someone through stopping a possible fire. A contactor had overheated and the arc chute was glowing bright red. I told them to turn all the breakers on that particular circuit off this removing the load. When I got there I found this. Obviously that’s been burning. IContinue reading “Arse!”
Oh shit.
A terrible terrible DIYer made a real mess of this installation.
High PSC’s…
I know this is nerdy stuff, but today I encountered the highest PSC (Prospective Short-Circuit Current) that I’ve ever encountered on an installation. 23kA was the figure I found, with an external loop impedance of just 0.01A So, why you ask am I sharing this? Let me briefly explain. All breakers have a maximum “breakingContinue reading “High PSC’s…”
Hard working day.
Changed all 27 lights in this building. Every single one had to have the hole tidied up as the old holes were really badly cut and not round.
Hate hate hate!!!
When a system is getting false alarms it’s always really irritating. Thankfully this place has CCTV so we searched through the system and found sunlight streaming through a shutter door to be the likely cause. We’ll see over the coming days.

A lovely Schneider Acti9 fitted to replace a pair of old Crabtree C15 units, complete with RCBO’s where the circuits would take them.Continue reading “Project “tidy up””
CAT5…
I hate crimping these things. It’s so annoying when you think it’s all good and then you realise a pair of wires have jumped over each other.
Rewiring complete… for now
3/002:365 – Shocking Originally uploaded by Last Human Gateway We now have lots of new sockets, and lights working throughout the house again after I replaced sections of this stuff (pictured) with modern PVC cable. The stuff I replaced was in a really sorry state, with the insulation cracking off as soon as I touchedContinue reading “Rewiring complete… for now”
A Busmans Holiday
2/362:365 – Busmans Holiday Originally uploaded by Last Human Gateway Yesterday and today I’ve been doing general electrical work on our own house (yes… our own house). I’ve fitted 4 new power points (kitchen, living room x 4,in 2 places, landing) and have had to disconnect two lights in the house because the wiring isContinue reading “A Busmans Holiday”
