What is a whole house surge protector?

by ct_acoustic_frontier July 06, 2022

A whole house surge protector is a device connected at your service panel that provides protection from 'big' surges such as lightning strikes. Most residential houses are supplied with two 120V legs and so a whole house surge suppressor designed for such an installation would typically have 'four mode' protection: live 1-neutral, live 1-ground, live 2-neutral, live 2-ground. Some products add additional live1-live 2 and neutral-ground protection to become a 'six mode' device. Commercial facilities may receive 'three phase power' which will require a different device. The maximum surge that can be expected at the service entrance is a C3 combination wave of 20kV, 10kA. Whilst lightning strikes can be 200kA this type of current does not reach the service entrance due to operation of utility surge arrestors, arc over to ground at the service entrance and insulation failure. What high kA rated surge protectors typically give you is longer lifespans, though much depends on the SPD and the protection mechanisms it uses. Basic whole house protectors are sold at the big box home improvement stores. We, however, recommend the Environmental Potentials EP-2050 which is a more sophisticated device that has the benefit of providing a first tier of noise reduction for your system.

Much confusion still exists about what a room correction product does, what problems it can (and cannot) solve and therefore its 'place' in a modern high quality sound reproduction system. Part of the challenge of understanding room correction is that it requires a reasonable level of understanding of sound quality, acoustic science, acoustic measurement and psychoacoustics (how humans perceive sound). The majority of the articles I have read online or in print magazines do not cover the fundamentals in enough depth to allow the curious and committed reader a chance to understand room correction on anything more than a cursory level. By the end of this article I hope that you will have learnt enough to judge for yourself what room correction can and cannot do and how best to apply it in the context of a world class music or home theater system.
