Well done chaps, this is a really simple and effective video displaying the benefit of the volt free contacts and how they can easily be used to help a client or their maintenance team to understand the status of the SPD, which must be visually inspected every 12 months. It also shows the benefits of pluggable SPD's. Great stuff.
Loving the cardboard drawings as always. I am fitting SPD's on every consumer unit change now (not done any 3 phase as yet) I have started not mentioning them to clients when pricing (as to many started trying to not have them) i just fit them and tell them of the benefits afterwards. I do prefer the Hager prefitted ones (off main switch) as no way of turning off independently but it would be good if they had a built in audible indication of failure built in
As you said, the fact that the green light remains on even if the SPD's breaker is open could be a problem. I suggest that this problem could be solved with an auxiliary contact on the breaker that turns on the red light also when the breaker is open!
I hope the domestic surge manufactures have noted this as most home owners need a light to go by as most wont even test a RCD test button let alone check a flag has changed colour?
Most domestic consumer units are sited in poorly lit areas, it'll be very difficult for the homeowner to be able to see if a small tiny window on the front of the SPD is green or red.
Very interesting, might be worth giving a brief overview of cost and time taken for your installation. Anyone interested in implimenting this would then have a point of reference they could work from (I realise all installs are unique!).
I am speaking purely from a consumers point of view here as I am not a sparky is that I would like to ask if a qualified electrician could also install within the light indicator box a siren for audible warning of the system failure. Secondly I think these kind of the indicating devices should be installed in domestic consumer units and even RCBO's should have an outside indicator system whereby consumers like myself know when to test the RCBO RCD function, have a service light to denote when a service is due on the system and also a SPD test indication light. Because this would help us consumers know when to call a sparky in to service the system or to replace a SPD Cartridges. Because I think we can all agree that with my knowledge gained on this channel and other 18th Edition states us consumers have to have a meter consumer unit meaning out of sight out of mind thinking. So I think as consumer I would appreciate a panel of indicators and warning beeps to ensure I am testing and maintaining the system properly. Anyways sorry for the long comment.
Could you investigate further into the installation of Type 1 SPD in a domestic consumer unit, rural overhead supply, I'm getting mixed messages that they should be in their own enclosure. For instance outside meter box with switch fuse 3m of tails to consumer unit. Should the Type 1 go at the origin in the meter box! with the switch fuse or in the consumer unit or in a separate enclosure at the consumer unit. Thanks
The metering kit is supplied with crimps and ferrules - the connection to the incoming isolator is via some fork crimps which attach under the screw head of the terminals.
Very good video , I find an interrogation push button would be handy on the green "ok" bulb as it will typically be on the whole time and I tend to find these Bulbs burn out the most
On single phase most of the ones with plug in cartridges seem to have the contacts. The single modules ones don’t - we first discovered the contacts when we looked at a Wylex unit - ruclips.net/video/B69R-yY6_14/видео.html
Could just use neon led indicators in red and green and put them in a 2 gang (single gang box) grid faceplate, just like a switch. Add a label, Bob’s your uncle.
I fixed an spd today and did not wire the auxiliary for monitoring since I doubted if I could use an AC or DC life conductor to feed the comon side of the auxiliary
What is the maximum load that the remote indicator connections can take? I ask cause I plan to use them to keep a contactor coil energised till the spd device failed which then would fall out the contactor.
The metering kit in this board is connected to the incoming cable. This is where we connected the indicators. The metering supply has its own fuses in the DIN rail blocks.

Great video, good idea with the indicator 👍

We put some links to the parts we used in the description. It’s about £20 of bits at RS prices.
every days is a learning day

You could change the indicators for siren etc

We will do some further investigation and see what we can find out.
Having to deal with the national exception code (NEC) myself, it would be fun for us to see you do a series showing what you think of our rules.
That sounds a great idea Kirk - can you drop me an email - gordon@efixx.co.uk - we can then explore the idea 💡 👍
Good video boyoz, surge with a nc no contact very handy to know, nice one.
Thanks
the feed for the meter have you used any sort of ferrule as you have a the main tails along with a smaller conducter feeding the meter?

You should get 100k hours from a quality brand of LED indicator > 10 years.
Interesting, maybe better to fit a buzzer to provide an audio clue as well.
Similar on a fire alarm system, not the Sounders. The buzzer. 😳
It will be wired the same
Do you have a video fitting 3 phase spd decide into a pre-wired 3 phase board? Thanks
I shall look next time as we fit SPD's on 99% of installations ( commercial) never knew that thanks, guys. Are the connections on the domestic to?

It would be possible with the use of at least one other relay to default to the red indicator if the supply to the surge protector was disconnected.
Good idea

At my work SPD voltfree contacts get connected to the BMS system.
👍👍👍
Tell me about the indicators of surge protection , if its showing red ticks what does it mean?
Can we test these surges with Magger?
What is the maximum load that the remote indicator connections can take? I ask cause I plan to use them to keep a contactor coil energised till the spd device failed which then would fall out the contactor.
Usually the minimum load of the SPD contacts is between 1 to 2 amps, but you can use an auxiliary relay to energise a contactor coil.
When you turn off the main breaker how do the Indicator still on
The metering kit in this board is connected to the incoming cable. This is where we connected the indicators. The metering supply has its own fuses in the DIN rail blocks.
👍
Is spd is open ckt under normal condition.
Arey the indications same for PHoenix contact SPDs
👍🌲
🙏
Does any one make a phase spd module and inclouse do a retro fit
Maybe better just to have fail status rather than a green led telling you everything is OK 24/7/365.? Just a thought…..😉
