  • Perhaps twice a year I get down to around 1 week of booked work and I get just a little jittery, not too much, just a little, but enough to make me start thinking about popping an ad in the local paper (if that is still a thing). Then, within a day or 2, or […]

Contractor 1s price was 44,000 My firms price came in at 37,000 – this was priced on a per circuit basis plus digs ect… Another came in at 15,000! Obviously the client went for the cheapest. Interested to know if anyone else […]

  • Hi there, Can anyone recommend a simple, intuative software or system for tracking jobs and issuing job sheets for 3No. electricians? I currently use Google workspace for scheduling/calenders but this doesn't provide any means to database and track our jobs or issue forms (job sheets) for our engineers. I've tried the free trial on Tradify… […]
  • I have a business owner claiming his pc monitors keep flickering and its a non consistent supply of electrix. He doewnt say he trips thr rcd but says this is dangerous as his servers are very important. He uses protection and regulation devices on his equipment. Once I test at the board and at all […]
  • This is in a flat, the plasterboard at the back is the bathroom wall surface. Is it appropriate to protect the incoming and tails with a steal plate fitted behind the DNO board? Worry about penetration form the bathroom but also Eddy currents and heating of a steal plate. Obviously the CUs will be changed.
  • Hi all, as I said before I came back to the trade last year. I've been on a couple of jobs recently where the no longer used, cancelled, "cut off" Economy 7 supply was not exactly dead, in both cases testing just over 12V across the tails. Has anyone else noticed this?

  • I bought some outdoor festoon lighting a few years ago and the 2 pin connectors (male and female) have corroded so I’m going to splice the connectors together using heat shrink butt connectors.

  • Hi Ive been tasked with replacing a mains switch, which is fed from the cutout and in turn supplies a domestic DB. It’s a BS88 switch fuse which I’ll swap like for like, but the existing DB, which is plastic will remain untouched. There will be henley blocks installed between the switch fuse and DB […]
  • Hi everyone I wondered if you can use a meter in the garage to monitor how much electricity is being used? (The garage has SWA and a CU with RCBO’s and SPD fitted) If so would you place it before the CU or after? Any recommendations on what/which to buy please? Cheers (I’m converting my […]

  • Hi All, I'm looking to pick the brains of experienced engineers who have dealt with TT more than I have please. We have an installation on a site which may or may not be unique. There are four 12m x 12m units inline with each other, all connected as one building, with the plan to […]

  • Hi All, I have these old light switches. I understand this yellow / blue is the old pre 1980 colour scheme. Is it correct that: 1. YELLOW with a red sleeve is LIVE 2. BLUE with a red sleeve is NEUTRAL ? Thanks
