FAQ – Ground Busbar Frequently Asked Questions
Q1: What is the difference between Ground Busbar and Phase Busbar/Neutral Busbar?
Ground busbars are primarily used for grounding and equipotential bonding in power systems, ensuring safe conduction of fault currents and leakage currents; phase busbars are used for power transmission and distribution, and are the main current-carrying conductors; neutral busbars form the working circuit and operate in conjunction with the phase busbars. These three types have clear differences in their functional positioning and system roles.
Q2: Should the grounding busbar be made of copper or aluminum?
Copper grounding busbars have excellent conductivity and long-term stability, and are commonly used in communication equipment rooms, data centers, and indoor grounding systems. Aluminum grounding busbars have advantages in weight and cost control, and are suitable for some industrial projects or large-scale grounding systems. The specific selection usually needs to be confirmed in combination with the project environment and grounding scheme.
Q3: Can the size and hole positions of the grounding busbar be customized?
Yes.
In addition to the standard engineering reference configuration, the length, width, thickness, number of holes, hole spacing, and arrangement of the grounding busbar can all be customized according to the project's grounding scheme to adapt to different cabinet structures and installation requirements.
Q4: Is Ground Busbar provided as a kit?
In engineering applications, "Ground Bus Bar Kit" is typically used to describe the overall concept of grounding busbars and their installation configuration. The specific kit required for a particular project needs to be confirmed in conjunction with the grounding scheme and site conditions. It is recommended to coordinate with the business personnel during the project communication phase.
