System design requirements

The more information you provide the more detailed our draft solution.

1. What is the system voltage and wiring configuration?

Wöhner systems can be designed for both AC and DC voltages up to 1000 V. We can incorporate busbars and supports for 1, 2, 3, 4 or 5 wire systems.

Your system criteria
1 bar - Ground
2 bars - DC +/-
3 bars - 3ø
4 bars - 3ø+N or G
5 bars - 3ø+N+G

Example*
480 VAC, 3ø

Your system criteria

2. What is the total current requirement of the system?

Wöhner has busbar systems like CrossBoard up to 125 A, 30Compact up to 360 A, 60Classic and 185mm up to 2500 A and the Central Feed Unit up to 4000 A. Based on the current information we will indicate what flat or special profile busbar type is most suitable for your Project.

Parameters
12 x 5 – 150 A
20 x 5 – 362 A
30 x 5 – 500 A
30 x 10 – 756 A
TT500 – 1,200 A
TT720 – 1,400 A
TTT – 2,000 A

Example*
600 amps

Your system criteria

3. What is the main over-current protection device and where is it mounted?

Identifying the make and model of the fuses, the fusible switch, the molded case circuit breaker or the lack of a main over-current device (main lug only) will allow us to recommend the most space saving design.

Parameters
I.D.
Make and Model

Example*
ABB T5
MCCB
Busbar mounted

Your system criteria

4. Size, count and construction of incoming cables?

Wöhner systems can accommodate up to 600 MCM cables (300 mm²). For higher current ratings we will use parallel AWG conductors or propose insulated flat flexible busbar.

Parameters
AWG#16 to 600
MCM or Flat Flex

Example*
AWG 600 MCM,
one per phase,
into lugs on ABB
T5 breaker

Your system criteria

5. Define the system branch circuits?

A Wöhner system is best suited to applications with at least 4 branch circuits – the more the better. It’s all about power distribution to the branch circuits.

Parameters
MCCBs
IEC Motor Controls
DIN Power Devices
Fused Circuits
Power Taps

Example*
1x 100 A NH 1
1x 200 A NH 1
2x ABB T2
1x ABB T4

Your system criteria

6. Any size or space limitations?

The busbar system may allow you to fit your system into a smaller, less expensive enclosure. It’s a great way to beat the competition on system size and labor.

Parameters
Enclosure H x W x D
Panel H x W
Vertical or horizontal
Shipping splits

Example*
2000 x 1200 x 600mm
NEMA12

Your system criteria

7. Other considerations?

Does the system need to be UL508 compliant? Has a required SCCR been determined? Any International listings needed?

Parameters
IEC
UL 508
Up to 100 kA SCCR

Example*
UL508

Your system criteria

* Example: These responses resulted in the system quotation illustrated above. It was determined that the system would fit into a 48-inch wide enclosure. Six holes were drilled and tapped to support the busbar structure, dramatically decreasing assembly time.
