Hi all,
I'll be wiring up two small new builds, the customer is supplying all the materials, they supplied MK consumer units, the problem is it doesn't seem MK are doing SPD's for their boards.
Any one know of a SPD that fits MK boards?

Thank you in advance

Do you actually need SPDs on your installs?

You don't have to fit them just because they are the new buzzword.
Read the regs and risk assessment. Speak to MK regarding their board.

Have a look at Reg 443.4 as there is an exception from fitting SPDs and from doing the risk assessment (that will always come out on the side of fitting them) for single dwelling units (flats, houses etc.) where the total value of the installation and equipment therein does not justify such protection.

Just out of interest, can anyone recall an instance where lightning has caused transient voltage to damage equipment in an installation?

Just out of interest, how many of you know of an instance where lightning has caused transient voltage to damage equipment in an installation?
Difficult to prove, but does happen. Happens more in countries which have a higher rate of electrical storms.

There's a website that shows where lightning is currently occurring. It's quite interesting.

unless you live in the middle of India and experience large amount of voltage surges then it isn't necessary to install spd's. especially for domestic property. if you do need one then put it in a seperate box near the cu and install a wylex one

Some sweeping statements there!

The way I read the section of the Regs and after doing the calculations for my area they are required. Can’t see how to avoid it, unless anyone can point me to what I’m missing?

My coffee machine is more expensive than an SPD so I fail to see how a single dwelling could not gave enough electronic equipment to warrant an SPD being fitted.

To answer the op - any SPD will do. You would need to install a Type 2.
