Domestic Surge Protection

melon_collie

I was just looking for some advice. I was looking for some surge protection for a electrical circuit in my house. Can someone confirm for me that the surge protector below would be suitable?

Thanks in advance

the pu1c looks good for the main board
just the single-module(live) afaik for standard tn-c-s

if you're protecting equipment you can add surge protection locally
or AVR or UPS to cover brownout,over-voltage or mains backup

complicated

Protection is always about where energy dissipates. Either a surge harmlessly dissipates in earth. Or it hunts for earth destructively via electronics. Either that energy is earthed 'less than 10 feet' by a hardwire. Or earthed via a protector.

So where does that Radionics have the always required and dedicated connection to earth?

No protector provides protection. Either a protector connects the surge to what absorbs surges. Or it does virtually nothing

One can learn this from how telcos all over the world do it. To make direct lightning strikes irrelevant, you telco connects every wire to earth - via a protector - because the wire enters the building. Essential is a short connection to earth. And separation up to 50 meters between protector and electronics. That separation and short connection to earth essential for protection.

Homeowners do same by installing a 'whole house' protector from reputable manufacturers such as General Electric, Square D, Siemens, Leviton, or Intermatic. The Cutler-Hammer solution sells in Lowes for less than $50. Each has what is essential - a dedicated wire for that 'less than 10 foot' connection to earth. How does the Radionics get earthed?

they're wired parallel .one leg earthed

it's euros here btw:D

Parallel as in wire to wire? Parallel to what?

M cebee

SPD is wired L-E at board ,loads are connected L-N at board

N and E are common for TN-C-S
