But obviously you would actually need a pair of these...? To allow for both Left-handed and Right-handed applications....! A useful tip is to wrap a bit of PVC insulation tape around the handle of the Right-Handed hammer.. so you don't accidentally pick up the Left-handed one for the wrong...

Can't really tell off the photo what sort of dimensions we are looking at? But "Tri-head" seems to be a common name for triangular security bolts/screws.. e.g. https://www.alcomet.net/product/tri-head-driver/ Maybe worth an email to one of numerous companies who specialise in security type...

I'm surprised a school does much cash work nowadays? { side-note-thoughts:- My wife works in the finance dept of a local school, and very little is done with cash.... Basically they try to avoid having much cash on site and minimise any bank visits to get cash. Their school caretaker has...

Off on a slight tangent.... When I was a young-un my first memories of Dr Who were John Pertwee & then the classic Tom Baker with his jelly babies & long scarf.. And confession time.... I was so impressed with Tom Bakers Dr Who Scarf, that my mom knitted me long scarf in a similar...

Anyone with a reasonable level of electrical qualifications, and more than a couple of years of practical hands on experience working on real world installations.... Should have figured out the essential basic rules of working safely on any electrical equipment.. e.g. Assume every...

Is this a typing error... "May 2021", Or are you only just chasing up paperwork, three years after an electrical inspection has been completed? I am not aware of any domestic sized CU's that have any suitable location where an EICR could be left... If it is "in the CU" you would need to...

From my experience there are four typically issues; (1) Fan not strong enough. (2) Duct too long. (3) Unable to allow equivalent amount of air into the room at the same rate that you are trying to extract. (4) Fan not running for a long enough duration after the room has been used. (building...

I would agree with your assumption.. A typical broken ring fault rarely has all three conductors totally open circuit..?? I have been on faults with similar symptoms to yours, which have been due to a socket front removed because it was going to be inaccessible behind some furniture.. But all...

Nothing to do with earthing... as a clip on bracket that can fall off cannot provide any form of mechanically robust earth connection! Open backed cheap tat like those sort of lamps run the risk of the wires physically touching the back of the lamp.. which can cause problems of heat related...

Obviously if its a 2-way or intermediate light switch, a "red-on" indication could be either way? hence not really much use on a light switch unless it is a 1-way! And excluding those in-line table lamp sort of switches.. e.g...

When breaking a live circuit there will always be some element of arcing and sparking until the contact gap is sufficiently wide to stop the current flowing. Think about how lightening, or spark plugs, or gas hob ignition etc.. which illustrate the principle that electricity will jump across...

There is no immediate or potential danger of electric shock, injury, overload related fire etc.. that could make the installation unsatisfactory for continued use.. And there is no code required for an unswitched socket as the connected appliance can be isolated by simply unplugging it. So it...

The Op actually asked if they need to be "Earth Bonded" not earthed.. which for a question in the DIY area is quite a reasonable description of the problem they are enquiring about.. The posts makes no suggestion that they are looking at using copper pipes to earth the installation..?? A...

Factually incorrect information is probably not much help to anyone new to the industry trying to pass exams which are based on the current edition of wiring regulations NOT historic issues of BS7671.. Familiarity with, and 'usage of, correct current terminology can be critical when answering...

Nice.. (y) :) But have you got a calibration certificate for them??? :unsure: 🍻

From reading the info on the Amazon link, I cannot see where is states Peak values?

Maximum demand metering is more of a need for commercial / industrial applications.. e.g. https://www.businessenergyuk.com/knowledge-hub/maximum-demand-meters/ But similar problems to yours in residential (private and/or rental), are not uncommon.. e.g. this article...

A few points spring to mind.... Have you been given an invoice with an itemised cost breakdown? If not ask for one? On the one hand £150 for up-to 4 or 5 hours work sounds very reasonable.. (e.g. 4hrs @ £37.50 or 5hrs @ £30.00 per hour).. But on second thoughts your profile states you are...
