Cable trays facing the wall become larger
Cable trays are often treated as an afterthought, which leads to issues like insufficient space or improper routing of cables. Solution: Assess the cable load, tray size, and future expansion needs during the design phase. If the spacing between trays is too large, it can create serious issues. In this guide, we'll explore why the spacing might be too wide, the problems it causes, and practical. Steel cable trays form the backbone of organized and efficient electrical wiring in industrial, commercial and infrastructure projects. We aim to ensure your project remains secure and does. Running the trays on edge requires that you secure every cable to every rung of the tray.
