1) Brief Description: Many times, when installing Surge Protective Devices (SPDs) to protect groups of individual circuits, the situation arises where you might need to use several different types of units, or models in a small area. This may be because you have multiple individual circuits to protect, it may be advantageous to tie the ground or neutrals together on several SPDs, or all of the SPDs may need to be housed in a weather proof enclosure. This situation often calls for a custom assembly. Many times, contractors do not have the time or expertise to construct such an assembly, or having the contractor perform this operation may be cost prohibitive. Applications like these can be addressed by using the Pre-Packaged Assemblies, also referred to as “PPAs”, from Surge Suppression Incorporated (SSI).
