Choosing the Right Power Distribution System

Distributing power inside a panel or switchboard safely and compactly comes down to the right combination of busbar, distribution blocks and earthing. Choose based on current, short-circuit rating and how many outgoing circuits you need to feed.

Busbar Systems

Busbar systems with adapters let you mount MCCBs, motor starters and fuse switches directly on 60 mm or 40 mm busbars, saving wiring and panel space.

Power Distribution Blocks

Distribution blocks split a single incoming feed into multiple outgoing circuits with finger-safe, touch-protected terminals.

  • Panel incomers
  • Sub-distribution
  • Multi-circuit feeds
  • Control panels

Frequently Asked Questions

Common questions about busbar and distribution products. Our technical team can help with ratings and adapter compatibility.

Why use a busbar system instead of cable?
A busbar system lets you mount switchgear directly on the bars with adapters, removing the incoming cable to each device. This saves panel space, wiring time and gives a higher, type-tested short-circuit rating.
What is the difference between 40 mm and 60 mm busbar systems?
The figure is the centre spacing between bars. 60 mm is the standard for MCCs and switchboards up to 2500 A and above; 40 mm compact systems suit smaller panels up to around 250 A.
How do I choose a power distribution block?
Match the incoming and outgoing conductor sizes and the total current, then check the short-circuit rating with the upstream protection. Distribution blocks are available in 1- to 4-pole versions from 80 A to 500 A.
Do I need an earth bar in every panel?
Yes. Every enclosure needs a protective earth terminal or earth bar that bonds the door, mounting plate, gland plates and all outgoing PE conductors, in line with IEC 61439 and BS 7671.
Are busbar systems finger-safe?
Modern systems use covers and touch-protected adapters to achieve IP20 finger safety across the live parts, allowing work near the assembly with reduced risk.
Which power distribution brands does LED Controls supply?
We supply ABB, Wöhner, Rittal, Teknomega, IMO and Lovato Electric.
