Building a Reliable LV Panel? Here Are 12 Components You Can’t Overlook
Low Voltage (LV) panels are the heartbeat of modern electrical systems, ensuring safe and efficient power distribution in residential, commercial, and industrial settings. While large breakers and meters often steal the spotlight, it’s the small, often overlooked components that ensure the reliability, safety, and functionality of an LV panel.
At Daleel Trading, we proudly offer Elber Electric’s range of switchgear accessories — trusted by panel builders across the GCC for their durability and precision. In this article, we’ll explore 12 essential components that no LV panel should be without.
1. NH00 Fuse and Fuse Base
The NH00 fuse is vital for overcurrent protection. It safeguards electrical circuits from damage due to overloads or short circuits. When combined with a high-quality Elber fuse base, this setup ensures easy replacement and secure mounting, providing both safety and convenience.
Why it matters: Prevents costly equipment damage and ensures system uptime.
Neutral links allow safe termination and distribution of the neutral wire in panelboards. Made from high-conductivity brass or copper, Elber’s neutral links ensure minimal resistance and long service life.
Why it matters: Ensures balanced load return paths and system stability.
These small mechanical components provide spacer and insulation between parts like busbars or mounting plates. Elber’s precision-made hex spacer bolts reduce the risk of arcing and simplify panel assembly.
Why it matters: Maintains physical separation and alignment in compact panels.
Busbars act as the central conductors in LV panels, distributing power to multiple circuits. Elber provides solid, tinned copper or aluminum busbars with excellent conductivity and mechanical strength.
Why it matters: Reduces wiring clutter and minimizes voltage drops.
To keep busbars securely in place, high-dielectric busbar supports are used. Elber’s supports are made from thermoset materials, ensuring strength, insulation, and resistance to temperature and chemicals.
Why it matters: Prevents short circuits, mechanical sag, and electrical faults.
Fiberglass Reinforced Plastic (FRP) supports are corrosion-resistant and non-conductive, making them ideal for mounting and support in harsh environments.
Why it matters: Adds structural support and insulation in demanding conditions.
Used as covers or barriers in LV panels, polycarbonate sheets are transparent, flame-retardant, and impact-resistant. Elber’s polycarbonate sheets allow visual inspection without compromising safety.
Why it matters: Enhances operator safety while allowing visibility and access.
PVC ferrules are used to label and organize wires, preventing errors during installation or maintenance. Elber provides high-quality ferrules in multiple sizes and colors.
Why it matters: Improves wire management and speeds up troubleshooting.
Wire end sleeves (also known as bootlace ferrules) protect stranded wires from fraying and ensure secure termination in terminals. They are essential for proper current flow and long-term connection stability.
Why it matters: Prevents loose connections and improves contact quality.
These rigid, non-conductive sheets serve as insulation barriers or mounting bases. Bakelite sheets are heat-resistant and dimensionally stable — ideal for demanding electrical environments.
Why it matters: Provides electrical insulation and mechanical separation.
A small but critical tool, the fuse puller ensures safe and contact-free removal of fuses. Elber’s non-conductive pullers are designed for NH-type fuses and reduce the risk of electric shock.
Why it matters: Enables maintenance without power shutdown or hazards.
12. Cable Markers & Accessories
Though small, cable markers help maintain an organized system by providing clear wire identification. Elber’s markers are durable, heat-resistant, and easy to install.
Why it matters: Saves time during commissioning, inspection, and servicing.
Why These Components Matter for Panel Builders
While fuses and busbars handle the big jobs, it’s the accessories — spacers, supports, sleeves, and markers — that determine long-term reliability, safety, and serviceability. At Daleel Trading, we’ve partnered with Elber Electric because of their proven performance in demanding electrical environments.
Whether you’re building a new panel or upgrading an existing system, overlooking these components could lead to safety issues, breakdowns, or costly rework.
