What is considered the best type of surge arrestor for residential main protection and related let-through rating?

Tx, nmwirez

Probably the best available and reasonable for a low exposure risk such as residential would be Leviton. These would be available only at electrical distributors.

Review their Surge Protection catalog at:
Site:&nbsp PDF Library Home (http://www.leviton.com/OA_HTML/ibeCCtpSctDspRte.jsp?section=17132&minisite=10026)


A medium level product would be by American Power Conversion:
Panelmount Surge Protection Device, 120/240V, 40kA/ph (http://www.apc.com/resource/include/techspec_index.cfm?base_sku=PMP1X)

A high end unit, probably too costly for residential would be Liebert:

One thing to consider is even thou the panel may be in a home, is how close is the home to any commercial or industrial businesses. If your close to a factory of any size, or a large supermarket, then a medium size unit may be recommended, as the likelihood of larger surges or transients is greater than if the home is in a suburb or rural location.
