Proteus ones take up less space

I recently bought the amendment 2 brown books to do my 18th edition. Will these be no good now?

Good luck on the new stuff. With this new amendment I can now see myenergi telling you on a warranty claim “oh I can see a bidirectional device not fitted we cant approve the warranty”

Great show and tell thank you.

Get yourself a fuse, they don’t care.

I've always thought it dodgy when I saw installs have things like solar on the load side of an RCBO. I couldn't quite say what was wrong, from what I know about the way RCBOs are designed (not an expert), but it's always seemed a bit howyadoin.

Top man is back

Good to see you Mike. Hope all is well bud ⚡👍😎

How do you explain that AC is alternating for old devices so they won’t work for a fault that is in the reverse phase ! And since inverters only supply the busbar sub circuits have single direction power flow ( ignoring AC ) and have their appropriate protection as required. This is as daft as double insulated core SWA’s 🤣

Thank you for your time .

No wire strippers

I have already been C2'ing installations during EICR's because RCD's aren't bidirectional when protecting solar/ wind power which have burnt out on the solenoid. Initially it was because if the test button doesn't work = C2 but after Mark Allisons video last year I've been amending my comments to list "needs a bidirectional rcd". Biggest issue being that not every manufacturer is making it easy to find out and not every technical helpline has someone at the end of it that knows if their product is or isn't. Hats off to the chap on Efixx comments the other day that told me to phone M2, their technical helpline is one of the best for knowledge on their products I've had to deal with. Sadly the latest EICR with an RCD issue on solar I C2'd has gone radio silent, possibly due to the amendment dropping a couple days later and realising they potentially have thousands of installs nation wide which they're now liable for the design and rectification of.

Mike Page - Legend 💪

Look at you Mr black hat. Yes bro 💪

I asked engineers about this way back at the start of solar and everyone seemed to think it wasn't a problem. How come the mighty IET only now have got their arse in gear? Are they going to pay to put all the installs right?

EVEN A REWIRABLE FUSE IS BIDIRECTIONAL LOAD OF BOLLOCKS

Glad you're back boss!

So if you don’t use a Bi-directional device on solar installs for example it can damage the MCB, so the manufacturers have put into their warranty’s that if they break because of this it’s not their problem?

The unidirectionality of "usual" devices only comes from the fact that most RCBO etc. in the UK are based on a microcontroller, right? Reason for my question is I'm based in Germany and we are told that it absolutely doesn'T matter how you connect RCDs, RCBOs etc. and they do not have any markings on them whatsoever, whether one terminal is the load side and one the grid side of it (they are solely based on the electro-magnetic and bimetallic principle). Would love to hear your comment on it! :) Oh and by the way get well! Wish you the best!

Awesome stuff Mike

Good to see you bud!

Good to see you back on RUclips Mike. No need to apologise for lack of content, your true fans will understand.

Bi-directional RCBOs sounds like a good idea on circuits with microgeneration but… please correct me if I’m wrong …aren’t most RCBOs inherently bi-directional? They typically rely on a bimetallic strip for light overload, and magnetic coil for big overloads, plus a toroidal transformer carrying line and neutral with a detection coil to trip in case of an imbalance. I don’t see why any of these components would be directional? Is it really just a labelling issue?

RETURN OF THE MAC 🎶 good to see you and your knowledge back lad 👌

Yes Mike! Been waiting for one of your videos! Hope all is well dude 👍🏼

Comment on the BS7671:2018 A3 DPC - electrical.theiet.org/bs-7671/updates-to-18th-edition/ BEAMA Technical Bulletin - www.beama.org.uk/resourceLibrary/beama-technical-bulletin---connection-of-unidirectional-and-bidirectional-protective-devices.html

The double edged Knipex one has 2 different functions. Upper blade is for cutting isolation, making the cable smaller. Lower one is for the actual cut.

Not sure a hex key in the Knipex shears is the best way. Hex bit in a ratchet might be better and won't ruin the cutters.

But if the test Spikes are into dry ground, what will that measure ?

Is the time clock a normal one or an Astro clock ? reason I ask I had a job where the customer spent daft money getting the main contractor out 5-6 times a year to suit the seasons and summer/winter times. I fitted an Astor clock that shadows the area you are in sunset and sunrise time plus it automatically changes the summer winter times

Hey Mike its been nearly 6 months. Are you planning any video of reviewing this system over time? currently i am on a buy and cannot decide between these and Meross one. Take care!

Is this for TT system?

Youse guys don't do the tighten loosen wiggle tighten torque method ?

I find it handy to have one not only for bonding but to go round all the metal faceplates if any and touch off them to see if the earth is continuous

you may want to look into the DS203NC series from ABB 😅

That’s a Del Roy type job

Dno or supplier still not been out to reseal?

The inspection cover is pointless as the dno have only left you with a tt as its a temporary supply and will be redundant when the permanent supply is re installed.Secondly you dont want to be kneeling on that joint, your likely to over stress the old lead causing premature failure of the joint or cause a flash over

During connection there is 110 v appearing in earth line

Always connect neutral 1st when making it off into live cutout

2 errors here don’t run the earth in front of tails ( also don’t touch tails) 1667 is the maximum for additional protection. But 100ma time delayed ADS is a maximum of 500ohms. You may have to cover both ADS and Additional protection depending on safety assessment.

Interesting info from Google “A bubble level has a measuring accuracy of 0.5 mm/meter in both normal and reverse positions. As we have seen, a digital level has an accuracy of +/- 0.05 degrees from 0-90 degrees and +/- 0.2 degrees from 1-89 degrees. So there is almost no difference between them, less than would ever be noticeable by the human eye”

That previously intro was absolute 🔥I loved the drama and suspense it created. Not only is your sparkie game on point. Your production and editing is mint mate. 10/10 would recommend

At the end , your neutrals and earths , connect them together. but WE know what you mean....!!!

See so many electricans with gloves on...is there really any need for it...? wouldnt like the loss of feel

U will damage the edges on u brand new knipex shears doin that Deff a code v
