What about a consumer unit install or upgrade for a £1.00? https://www.ebay.co.uk/itm/Consumer-Unit-Installation-or-Upgrade/402287763432 Doc H

MCB:  Miniature Circuit Breaker,  the modern day switch type replacement for traditional wired fuses.  (fits into a CU).  CU:  Consumer unit or Distribution board where all of the circuit cables connected to the MCB's to obtain electrical power for the circuit. The items that you called the...

You are incorrect thinking a loose connection requires vibration to cause problems. Electricity always generates some heat as it passes through a circuit. Higher power means greater heat and loose connections also increase heat. As power increases and decreases during normal usage, the joints...

So while not exactly unexpected, HRH the Duke Of Edinburgh has passed away aged 99. Respect, condolences, and best wishes to those who are close family members who have lost a loved one. (All families no matter what the background will still be feeling loss and sadness just as any other...

Welcome to the forum, from your photo the water pipe appears to be plastic. But any contractor quoting to install a charger will, (or should), be doing a site visit to ensure every thing is adequate and compliant with current regulations to take the additional load that an EV charger will add to...

Agreed, Covid is without doubt a real hazard that requires some precautions and care to reduce transmission. But it is not an automatic death sentence, remember government guidance if you are infected is to isolate for a couple of weeks, which in 90% of the cases is all that is needed. And its...

This may require photographs before we believe you. (telephone numbers can be sent later).  To answer your initial question, if offered I think I would take the opportunity and recommend any close family members to also accept if they were offered the chance. The sooner this is brought under a...

If you are already competent and have a good concept of electrical science and theory, a formal PAT qualification can be acquired easily in a day, but its not worth a fat lot in the real world of employment. Whereas establishing if an installation is satisfactory or unsatisfactory for continued...

I would think there is further significant information we are not been told here. Any recent work undertaken, any fuse box replacements, is it MCB, RCD or RCBO that is tripping. Any other building related problems due to water damage, rodents, building work etc.? Doc H.

Not sure if it has been mentioned yet but any movement sensor used to trigger a camera or light can be susceptible to false alarm or nuisance operation. Some people forget to take account of things like warm air extracting from boiler flues that can trigger sensors. Or how many metres range the...

Duplicate threads merged. Doc H.

Please do not start duplicate threads it just clutters the forum. I have merged your two questions. Have you read the manufactures instructions for the devices you ask about? Do you have any qualifications, as your first thread was posted in the DIY section? It would probably help if you...

This is the catch 22, if you can't do notifiable jobs that will limit your possible work, and limiting possible work will mean its less cost effective to enrol for notifying you own work. And if you start accumulating customers, but then have to turn notifiable jobs down, you will then start...

Edited that for you. another one of the joys of predictive text. Doc H.

If using 4.0mm, the back-box depth and type of accessories becomes a key issue. Connecting a pair of 4.0mm conductors into some of these modern socket outlet terminals can be a right pain in the rear. And if it is a standard 25mm back-box and the customer has some slim-profile, hidden...

Whilst technically correct that 525.202 refers to the origin of the installation, (usually the supply terminals), if you are considering an average domestic dwelling, the real-world effects meter tails have on compliance with volt-drop is generally negligible.  Try calculating (mv/A/m) on the...

Who are you getting your Public Liability insurance from? I would have thought they could provide a combined package? Doc H

Back in the early years mobile phones used to have battery packs that could be removed, (and hence replaced), easily. So when your battery lifespan started getting a bit poor, you just fitted a new battery pack. {Similar to if your battery drill, or battery multi-tool needed a new battery.}  I...

Keep the local fire brigade on speed-dial if you do. If you read the manufactures instructions for each product you should find guidance to the type of circuit required for each. I would think the words; dedicated circuit, competent person and in accordance with current wiring regulations...

Was it a permanent live, or switched-live, that was shorted out to earth? If it was the switched live you may have just burned out the internals to the switch. Doc H.
