Are surge protection devices fitted before or after the main switch

 

[Taylortwocities]

Have a think about what the main switch does, and what it is for.
if you don’t know the answer, then maybe someone competent should be doing the work.

Hi L1Jay1 where do you think it should be installed?

Hi L1Jay1 where do you think it should be installed?

What about putting it in the closet ?

 

[Strima]

What do the manufacturers instructions say?

How about you guys take a look at his profile and maybe go a little easier on him... it clearly states he's a trainee... just because someone doesn't have the trainee tag, doesn't mean they aren't.

@L1Jay1 , maybe consider signing up for the trainee section of the forums. You'll get a trainee tag so everyone can see you're training and you'll get access to a trainee only area which only trainees, staff and mentors can access so you can ask questions such as this without getting this kind of response.

To answer your question, they would generally be installed after the main switch. The ones in most domestic boards are installed as close to the main switch as possible, many are supplied via a circuit breaker (I've seen 32A for all the ones I've seen) but some, Hager I think, are connected straight to the main switch itself. But as @Strima says... what do the manufacturers instructions say?

I’m simply asking the question

In the live boards the spd is before the main switch

What about putting you in the closet

Hi - normally the main switch isolates all the equipment in the board, is that what you mean?

 

[Ian1981]

The spd normally sits in parallel with the installation.
It should be capable of being isolated for maintenance purposes.

Sorry I meant a LVE board , I’ve seen a LVE board with surge protection already installed in it , the SPD is before the main switch in this board , this got me confused.

Sorry I meant LVE board , not live

When you say the SPD is before the main switch, do you mean physical position or actual wiring order though?

I was trying to think of a way of wording that @DPG, stupid hangover! ?

This picture illustrates @DPG 's point perfectly. Physically it appears before if you're looking from right to left, but wiring wise it's most definitely after the main switch.

in LVE , SPD is before main switch

In the LVE board it’s before main switch, I’m trying to understand this and the way it’s wired, it appears to be wired before the main switch aswell.

@L1Jay1.....just an observation.....constructive criticism even.....but I think you may need a little work on merging posts....possibly maybe?.....??
But I think @DPG and @SparkyChick has nailed it for ya here...
