Suggest you still check out the linking wire as discussed above. I replaced the stat a couple of times before I realized they were being "killed"

I had a similar issue with a TESLA immersion & thermostat which I documented on here. To cut a long story short, the final answer turned out to be the factory crimped link wire between the thermostat & the element. The crimp (hidden under a sleeve), was poor resulting in heating of the short...

The 'three limb' arrangement is pretty much the standard 3-phase arrangement. What aspect of three phase transformers cant you get your head around?

∆T means the difference between TWO temperatures, so, for example, the temperature inside your house is 25 C & the temperature outside is 5C then the ∆T across the wall is 20C. Myson are quoting the power emitted when the temperature difference between the hot water flowing in & the water...

An here in the UK... for a certain Car & van Hire Company that threatens to charge a fixed £2K excess fee for ANY damage if you dont take out their waiver.

^^^^^ What he said!

I think there is more to this ...... The transformer is probably producing AC ...the battery pack will be DC. You cant just connect the output of a transformer in place of a battery even if you match the voltage. Show us a pic of the 'transformer'.

I hope whoever fitted that PowerLok knew that the conductor should be secured into the conductive part of the connector with two grub screws (and alot of 'welly') and didn't just push the bare end in & tighten the gland at the back. I'd be checking the other nine ends very carefully!!

I think you may have a 4/6 pole machine - that would add up with the speeds you quote & I think the wiring would be like this:

I feel your pain! I spent a good number of my (younger) years on doing generation & distribution on the UK Music Festival circuit. Caterers always seemed to be the ones coming up with most...... "inventive" solutions to the power issues - anything from 16A male -males ("'cos you can't get a...

How long is the HDMI? Are the PC & TV plugged into the same socket outlet/4 way or are then in different sockets? If on different sockets, are on the the same circuit?

By the time the RCD trips ... the current is already flowing so the damage is done. The RCD is to help protect humans & against fire ... not to protect equipment. I think Id be looking for an open circuit CPC that is allowing a fault current to find a path via the HDMI leads outer screen.

You might have another problem..... Have you checked that a UK bulb actually fits in the lampholder? American lamps are E26 & European lamps are E27. ie. the have a (slightly) bigger diameter screw thread.

Have a look at 'ADILeakDetectiveMG' on You Tube. Some quiet smart methods used to find hidden leaks!

Well no. The Eco7 & Full time tariffs CAN'T share a common neutral - since they are fed from different consume units. (I agree that they share a common neutral in the sense that there is only one supply into the building BUT after that is split to the two consumer units, E7 & normal rate, you...

The reason for this being at the front of my mind was that, for the first time in over 2 years, the immersion stopped working again in the early hours of Friday morning. At the bottom of this email is the log file (plot1) from the last week. The deep 'V' shaped dips are someone taking a bath ;-)...

I too have had issues with Tesla immersion heaters & thermostats, although in my case this is with a top mounted 27" heater & 11" stat. I have written about this in a previous thread but I cant find it at the moment. My issue was with the anti-boil over heat portion of the stat randomly...

Converting an 'intermediate' (DPCO)switch to a 2-way (SPDT)?

440Hz is waaaay too low for a SMPSU. They operate in the KHz range - around 40kHz being a common switching frequency.

Another way would be to have a central (mega) junction box (like the good old Hartley Octopus from years gone by) at some central point (or one per floor). From here run 3C+E to each switch & to each light point. You now have many options - a neutral can be made available at each switch point &...
