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.

Dracule1,

Why not MOVs?

I think the whole house surge protectors are made of silicon oxide vasistors, which is suppose to be reusable over and over, unlike MOVs.

Dracule1,

Not sure about that. I believe most are MOV type.

Eaton (Cutler Hammer), Square D, Leviton, and Siemens, use multiple MOVs.

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.
