I recently had an SPD consumer unit fitted, twice now when I have been using the electric shower, power has been cut for a few seconds then comes back on. I don't think it's a problem with the shower as the light on the ceiling pull cord goes out as well. Any ideas, so I am pre-armed when I...
Hi
Have done some additions to an existing multibuilding non domestic site. I noticed no SPD on the mains intake side, they are in a reasonably high lightning strike area. So suggested they should have one. Did some research and was going to use the Hagar SPA4501 along with the metal IU4...
Going to be fitting a three phase SPG at the origin of a supply. I have solid coper standard 25mm tales that come out of the head into an isolator and then fine stranded 25mm single insulated cables that run from the isolator, within flexible conduit to the Dis boards.
They have used a crimp...
Iv been tasked with upgrading a 16th edition board with a schneider 6 + 8 way acti9 board with spd protection.
SPD was specified for me so I dont have to perform the calculation, however, I am stuck with the specifics of the devices themselves.
Firstly, can the device hang of the back of an...
Hi Guys, Recent EICR carried out at a Church & Hall. Would you code no SPD present at Supply origin & should the Lightning Protection System be connected to the Main Earthing Terminal via another SPD.
Hello and thanks for the interest. I have a little dilemma and was unable to get an answer anywhere.
I'm trying to fit a SPD and an over/under voltage protector to my existing "Main Switch" and "RCD" setup. my question: is the location of the SPD and surge protector correct? thanks
I've been asked about providing inline surge protection for the UPS supplies in numerous network cabinets around our factory and I'm hoping someone more experienced in this might have some suggestions.
There are about 15 cabinets dotted around the factory containing various switches and routers...
Evening..
Just wondering if anyone has any links to an explanation of the above that a customer could understand, I'm getting a bit peed off trying to explain the benefits only to get a look back as if to say 'why is this salesman trying to rip me off'?
Cheers
hi guys. Just wondering if i can ask for some advice. Looking at fitting a contactum spd in an existing board and the instructions say to fit the spd to the right of the main switch, but the previous electrician has not left a spare way there so was thinking of having the mcb and the spd on...
Hey guys,
Came across a retro fit SPD today on a BG board. It was a dual split board and the MCB for the SPD was hanging off the end.
I've not retro fitted an SPD but I would of though the MCB should be off the main switch at the head of the install? The blue book just says at the origin.
I...
Evening all,
This has probably been answered somewhere here, but in case it hasn't... I have a Fluke 6500-2 and had trouble testing SPD extension leads as you cannot drop the voltage to 250V using the IEC lead test button. I found a way to set up an auto test sequence to include EB and 250V...
HI I am looking at a job where the CU needs an upgrade as its plastic and has no spare ways for the circuit I will be installing. Looking at giving customer options so will be quoting for metal CU, integral SPD and looking at combined RCBOs and AFDDs for each circuit, looking at the spec for...

Question is does the line from the spd connect in same bus bar connection on main switch???

Hi everyone ,
Only my second post and hoping to get some information on installing an SPD Type II incorporated within a new consumer unit upgrade I will be doing next week.
With the new 18th edition regs I’ve been generally installing RCBO consumer units with integral SPD as standard .
The...
I'm about to rewire an empty house, with no electronic equipment or anything else plugged in or installed. Does this mean I can omit installing an SPD because the value of the equipment that could be damaged is less than the price of installing the device?
"For all other cases, a risk...
