Full Description

Scope

This guide covers the application of surge-protective devices (SPDs) for installation on the load side of the service equipment for 50 Hz or 60 Hz, ac power circuits rated 1000 V rms or less.

Purpose

The purpose of this guide is to provide users, specifiers, installers and manufacturers with guidance on the use, selection, application and installation of SPDs for installation on the load side of the service equipment for 50 Hz or 60 Hz, ac power circuits rated 1000 V rms or less.

Abstract

Revision Standard - Active.Guidance is provided to specifiers, users and manufacturers of surge-protective devices (SPDs) about the application considerations of SPDs to power distribution systems and associated equipment. This guide applies to SPDs to be connected to the load side of the service equipment (and main over current protective device) of 50 Hz or 60 Hz ac power circuits rated 1000 V ac or less. Information on surge origins, effects of surges, number and magnitude of surge events, location categories, power distribution system (PDS) configurations, grounding and bonding, SPD specifications, SPD ratings, SPD characteristics, SPD lifetime, interactions of SPDs with a PDS, and SPD coordination considerations are provided in the guide.
