Whole house surge protection

I'm thinking of having an electrician install one of these devices at the service entrance of my house. I get frequent thunder storms. Does anyone know what these are made of? Do they use inductors? Reason I'm asking is I do not want any device that can limit dynamics of my audio system. I've looked into ZeroSurge, SurgeX, etc that use SMP, which seem to be ideal compared to devices using MOVs. But all of these use inductors..and some who have used this type of technology have complained of dynamic restriction and collapsing of soundstage. Thanks.

Yes I did. couple of things are holding me back. One is the amount of max surge current it can handle, 12.5 kA. Other surge arresters for residential applications I've seen are 80+ kA. And it has no warranty against damage.

Dracule1,

Which ever external mounted SPD you go with the unit protects best when the wire leads from the SPD are as short as possible.

If possible the breaker used to connect the SPD to the bus of the electrical panel should be installed as close as possible to the load side of the main breaker as well as the neutral/ground bus bar. Inches matter!

Sharp bending of the SPD wire leads must be avoided.

As for the Eaton CHSPT2ULTRA you will notice the manufacture recommends a 2 pole 50 amp breaker be used for connecting the the SPD to the electrical panel bus.

Thanks Jea. It's a little too technical for me, but I can at least have an idea if my electrician is incompetent after reading the article.

Lifeengieer, I agree with you. But I am looking for a surge protector, first and foremost. Having some sort of filtering is nice to have.
