Regrettably that won't work. The clamps (current transformers or CTs) measure current flowing in a single direction. If you clamp the mains lead to an appliance then you'll be measuring the current in the live wire minus the current in the neutral (as it's flowing in the opposite direction), so...

It doesn't REQUIRE 3-phase, we just happened to have it and 3-phase GS heat pumps are just that little bit more efficient that single phase, so incremental gains. It all counts. We recently had a full service and firmware upgrade etc. The actual CoP was measured at that time (needs a fair bit...

I have just installed one of these, mainly for our three phase utility feed... As an electronics engineer and software designer, the system architecture appealed. It's a good system, but is USA-centric at the moment and is faily new to the UK market. This means that several European norms are...

Tragically, we had exactly this with our pointer: Thus was while I was working in the Gulf (Dubai/Oman) and one of our sons sent me the photo of what the dog had done. It also ate another sofa...

Good lord. Folk are slow. May 4th is International Star Wars Day, as in “ May the Force be with you”. Think about it. If you are still lost, stop reading now and move on to the next comment. The painting is a modified version of “American Gothic” by Grant Wood American Gothic - Grant Wood...

We have a separate clock for E7 that trips the main 3-phase meter between high & low rates - it's set explicitly to 00:00 - 07:00 GMT. You can see it in the photos I posted. EDIT: Uh, no it's not visible - it's just off the top of the photo of the meter cupboard.

I have replaced all 52 x 50W halogens (mostly MR11 with a few GU-10) with decent 5W LED GU-10s. Painful job - all 12V halogen transformers removed and all fittings changed to GU-10. We have three-phase to the property, have a couple of outbuildings and use a ground source heat pump, so...

Desk is lovely but... pretty please, get yourself some curly cable ties or similar

My only comment to the complainers: There are probably more posts whining about the BMW comments than the BMW comments themselves. Similarly, folk complaining about not understanding other people humour is just wasted space too as are all the comments calling for yet another joke/humour...

...but only 500 of the original E30 LHD homologation series... As I'd been working in France & Switzerland, I'd been driving a RHD car on the continent, so driving a LHD car in the UK was easy. I did improve my driving as I bought progressively more sporty cars - lots of track days with 1-2-1...

Back in my bachelor days (1988 - "E" reg) I had a Lachs Silver E30 LHD M3 as a company car and my daily driver - one of the only 500 built as a homologation series. Total BEAST ! It was Top Gear's "Car of the Decade". Loved it. Brilliant motor... especially as I'm 6' 4" tall and there are few...

You have a PM

Thanks, but it's collection only and a looooooooong way from me...

Still hoping!

Looks to me like a jacketed slug from a .223 (Remington) or 5.56mm (NATO) round. Very standard hunting round if you're after bigger game like deer. If your timber came from woodland where there's hunting, finding slugs is unusual but not exactly rare. We have an oak window sill which also had...

Made a sauna out of two donated large sheds (from local school, made into one good one), a hardwood framed double glazed patio door, our old freezer's door, some strips of steel from the old freezer, a lot of reclaimed insulation, some reclaimed plywood, some end-of-line tiles and two new PVC...

I used to run IT and infrastructure for hedge funds and other city companies. One lovely building just off the Strand and overlooking the Embankment Gardens had a major mouse issue. They'd got under the false floors of this 8 story building and developed a taste for fibre optic cable. We only...

You need timber treated to UC4 (Usage Class 4/BS8417 [includes BS EN 350:2016]) - see UC4 Timber Preserving Treatment, i.e. UC4 Gravel boards, e.g. Wooden Gravel Boards | UC4 Longlast Timber | Gravel Board Timber Most UK treated (tanalised etc.) timber is UC3 which is not suitable for long-term...

Made a Valentine's pressie for SWMBO. First attempt at stained glass... used some offcuts from a glass merchant, hence the mix. You can guess the initial of her first name... Simple oak frame and zebrano splines - lead edge is rebated into the frame. Oak is from some floorboard offcuts leftover...

Fair points!
