SPDs do i need to fit them?

[Ian1972]

Hi, I'm installing a new circuit in domestic dwellings for various housing associations my question is do I need to fit an SPD or would it be the responsibility of the housing association, the circuit supplies equipment in the garden I'm running a 2.5 twin and earth through the house fed from a B16 MCB or RCBO depending on the fuse board it goes to an external rotary isolator, thanks in advance for your replys

Personally, if I was just installing a new circuit, I wouldn't go to the extent of installing an SPD unless it was specifically requested.

That being said, it appears you are installing circuits specified by someone else... the designer... maybe bounce the question to them?

Running a 16A radial to an external location…. To a rotary isolator?

What the heck for?

Run to an external socket maybe.

Are the housing associations providing hot tubs now?




Possibly Air Source Heat Pump now I think of it

That was exactly my thoughts.

Hi yes ASHP

I've just been doing a SPD risk declaration and getting the customer to sign. I'm doing these for new circuits and alterations. It's only a couple of tick boxes no calculations. It also prompts thought about what type is required.

TBH I'd be more concerned about the correct type (Type A) of upstream RCD being in place than I would about SPDs.
Especially if the ASHP uses an inverter drive.

I'm not giving an option with RCD type. If it's the wrong type I'm upgrading them. If it's an easy upgrade a SPD makes sense.

Why you using 2.5 with a 16a? Could use 1.5.
