Why whole house surge protectors are not enough


TL;DR:

One measure of a surge protector is the clamping voltage. That is, at what voltage does the surge protector actually start to work. Whole house surge protectors are limited to no less than ~ 600 Volts (instantaneous) between a leg and neutral or ground. That’s up to 1,200V if symmetrical.

The best surge protecting strips and conditioners clamp below 200 Volts.

Please keep this in mind when deciding whether or not to use surge protectors at your PC, stereo, TV, etc. in addition to a whole house unit.

I wrote more about this here:

No manufacturer of whole house surge protection claims that their devices alone are enough for sensitive electronics when you check the fine print.

Sorry, current. My Gray was an old model from 2008. The Gray had chokes. Chokes compress dynamics I've been told. 

I have a 30A dedicated line connected to my Uber Buss power conditioner with a 30A Neutrik connector.

My UBER Buss does a better job with noise than the Gray. Power Factor Correction of 1 if memory serves me.

Caelin Gabriel of Shunyata advises the whole house surge suppressor at the breaker box, and no suppressor at the equipment rack and Garth Powell of Audioquest feels strongly for the opposite due to potential RF noise.

When used in series, possibly, but that’s now how RG’s chokes worked. They are in parallel.

PS - You should open up your Uber Buss. I’m sure you are going to find a whole bunch of chokes and coils if it does anything at all. 😁

Facts, the National Electric Code requires whole house surge protectors since 2020 AND recommends point of use surge protection devices for sensitive equipment.

The first post explains why they recommend both.

While the NEC requires whole house surge protection, it does not force you to use a surge protector for your stereo or TV. That part is up to you, but I’ve explained why the two are complementary as opposed to exclusive.

Also, anyone who says that a whole house protector could cause RF noise is full of it.

No I won't find any chokes. The designer ran through everything with me. Please don't comment on something you know nothing about. 😁

That should tell you all you need to know about these two. They don’t know what they are talking about and are giving bad if not financially dangerous advice.

I would say the same thing about the person who wrote this. They either don't know what they are doing or are lying.  I get the impression the UberBUSS is like the BlueCircle and TLP products. Stack as much capacitance across the line as possible, safety be damned!

"UberBUSS is a power filtration unit quite unlike others on the market. It is filtration only. There are no MOVs or other suppression devices to color the neutrality and introduce noise into the circuitry.
