Introduction to Sandwich Panels in Electrical Prefabrication     Electrical prefabrication depends on a few factors: predictability, repeatable quality and protection of critical systems. Sandwich panels have become a core building material that supports all three, especially as prefabricated electrical infrastructure continues growing in scale and complexity.    What are sandwich panels? At a basic level, they’re multilayer panel systems made from two metal skins bonded to a

Reliable underground utilities don’t happen by accident. Power distribution, communications and essential services all rely on carefully planned systems that protect cables from damage while allowing for safe access and long-term growth. One of the most important (but often overlooked) components of this system is the duct bank.    From city streets to industrial facilities and mission-critical environments like data centers, duct banks provide the structure needed to keep un

Temporary power may be temporary, but the risks of poor electrical connections aren’t. That makes purpose-built generator tap boxes an essential part of modern power planning. What is a generator tap box? At its core, this equipment (sometimes called a generator connection box or generator docking station) is a safe, centralized point where temporary or emergency power from a generator ties into a building or jobsite electrical system. Rather than running loose cables or buil

On large commercial jobs, efficiency often comes down to the smallest components. A 4-outlet box, more commonly referred to as a commercial 4-gang outlet box, is one of those components that keeps projects moving. It’s designed to house four devices, for example, receptacles, switches and data ports, within a single electrical box, supporting higher power density in busy spaces. In offices, hospitals, schools, warehouses and manufacturing facilities, multi-gang boxes are a mu
