If you divide the volts by the resistance, that will give you the amps....Change the amps to KW and check against the motor plate... In this case 400 volts divided by 45 which is about 10amps .... then take 10amps * (400 volts divided by 1000watts) = 4 kw motor. Also, it is worth noting that one test that people don;t do is checking that you are not single phasing the motor. Make sure that you have all 3 phase's at the motor. It is common that a pole will fail across the contactor,. Test at the isolator incoming. Also, check that the motor is not seized.... Undo the fan shroud at the back of the motor and spin it by hand. Lastly, Check the motor plate, 3 phase motors have varied winding configurations like star delta, PWM, delta, delta..... etc

mmm all that lurrvly scrap copper 😜

wot a load of bollox, subscribed :p

Thanks, great video

17:28 the definition of "do what I say, dont do what I do" 😂😂😂

I love fucking around with the big stuff. Great tips and love the honestly. I always get my apprentice to watch these types of videos

Thanks for the video, helped knock off some of the cobwebs. Possibly a video looking at a bad motor in the future?

Have you got the link to those clamps/brackets for the panels? Cheers

Why didn't you start at the new cabinet and work backwards? Could have kept the lugs on. Could have saved cutting precious cable for any future changes. Would have left a 'nest' at the green cabinet but would that have been a real problem? Genuine question.

With the phase conductors going through separate holes isn't this going to give you issues with eddy current heating? Or does the gland plate being ally mitigate that?

serious work done here

Great video, when we do heat shrinking for 33kv joints we always shrink tubes from centre out to work any moisture that may have accidentally got into the tube out to the edges. Just how we were taught thats all. 👍👍

First time viewer and subscriber here. If only I knew about the tip of the constant pressure spring from the jointing kits years ago. Would have saved the copius amounts of insulting tape used and then binned. I like the trigger attachment for the crimper/cutter heads. Will be watching more of the videos and I like the technical term for the trefoil layout. Nice (real life) site work complete with the banter.

i love the electricery bit @1:50 haha

Respect the crimp Excellent video

Shelly em are awesome. Also lots of esphome projects that can port data in realtime to home assistant if you do want data and control over your inverter. But truthfully its all a nice to have.

Hi Jamie, is there anything against using standard short shank lugs on fine stranded cable? ive always been taught that for fine stranded cable you need to use the longer lugs, like the klauke dynamic range. longer shank and more indentations. curious to see what your thoughts are on this

Measure 20 times, cut once 😃 cool stuff

That b’stard music is stuck in my head. Dick 😂

At least the PV fields here in the Netherlands have all that mess inside environ-mental save concrete and steel boxes.

Hi Jamie, I'm sure Tony from Jointech Cabling would be happy with your work, I don't know if you watch his videos at all? Nice hydraulic crimper matey. Regards from the old sod

Great electrical content, sir. 💪🫡

"Never drill a lug, never drill a lug out" Why the fuck you lying...!! LMFAO 😂😂😂

Think you will find those Mac ladders were the property of K star electrical services bought from the Mac man in Bingham a long time ago. Awesome ladders.

So what current are those good for? Inverter must be mind blowing.

This maybe a absolutely stupid question but to save the issue with the gland plate and individually why not use a Watertight gland block similar to that used aboard ship bulkheads as I assume you cant use large ducting due to heat build up, neat job but seems that part of the job is a design ballache that could be avoided at the early stage of the inverters manufacture

So very interesting... Liking the hydraulic kit... Hope to see you use that on a house rewire soon

I wondered how they grew so many Solar Panels. How long do they take to grow?

This is exactly how I explain it to young engineers. Should do video on cascadence with similar method of explanation haha

I wonder how many of our politicians realise what it takes to upgrade our infrastructure! They talk so glibly about upgrading....... They simply don't have a clue. Good video again Jamie.

You shouldn't mark only the nut. You should always draw a STRAIGHT line down the thread and onto the nut, that way if it's working itself loose due to a fault, vibration, harmonics whatever you can diagnose it early.

You can also use hose clamps, a bit of wire twisted on. Also Alroc and the like also sell LV stripping tools and an exhaust cutter can help you strip your cable round.

Great work mate,nothing wrong with throwing a few fucks around 😆

Where are the plastic coloured tabs from ? All I am finding are the crappy paper ones

What's your thoughts on voltage optimising for air con and heat pumps?

This made me laugh. Brilliant. i might have to give you a follow!

Even with no load, USB sockets show up like birds round a bag on a thermal camera

Part 2 was absolutely fucking brilliant - I went and built a test rig after watching it haha. Great content 👍🏻

the grass is always more colorful on the other side of the fence

Super F*** instruction ! THANKS.

😂😂😂 it was never in question

Good vid. People ‘research’ ‘stuff’ on the internet, play top trumps and miss the bigger picture. The internet just makes stupid people stupider. This is why I haven’t done domestic jobs for years.

You didn’t do your apprenticeship with Cannon Electrical by any chance did you? I had a similar path to you of working at Nottm University and then spent a bit of time over the road at QMC. Well, i say a bit, probably 18 months of my 4 year apprenticeship i spent there! Still have nightmares about those service voids 🤢 Nice video mate and very true what you say about taking chances and opportunities.

Awesome video mate, thanks for sharing this with us. Nearly had me crying like a little bitch at the end!!! It's true though, the main major push to do manly shit when I was younger was the fear of being called a p*ff if you didn't have the balls to do it!!!

Proper tickled me

Good video and great advice mate

😂😂😂 love it, I wanna work with you!

Good video. I enjoyed the pictures at the end.Your right , and sometimes you need reminding of this

Thanks for clearing that up 😂😂😂

Hi Jamie, this is one of your best videos ever, I have aways seen through your normal persona to see what a genuine nice guy you really are. Regards from the old sod.
