Bus duct: segregated vs non-segregated

Bus duct: segregated vs non-segregated

Bus duct: segregated vs non-segregated

(OP)
Busduct is way out of my comfort zone, but I was asked to provide it in a package anyway. This was a low voltage application and anticipated load is 2000A.

The requirements I was working with called for "Non-segregated" busduct but most vendors I spoke with only wanted to talk about "segregated" busway.

I am unclear on the application strengths and weakness on the two products. Where would one type be more applicable than the other.  

RE: Bus duct: segregated vs non-segregated

The phrase segregated busduct is normally only used with medium voltage systems (each phase is seperated by steel from any other phase). Almost all standard low voltage busduct is non-segregated (no steel between phases).

Terminology may also be a problem. Many people also refer to busduct as busway.

RE: Bus duct: segregated vs non-segregated


It depends on whether you have a <660V or> 660V application.

At high fault levels <660V I recommend GE Specta Busway. At >660V Non segregated busduct will be suitable.

RE: Bus duct: segregated vs non-segregated

Suggestion: Generically, the nonsegregated buses are supposed to be less expensive, especially for medium voltages. Segregated buses or bus ducts tend to be more expensive and used for lower voltages as well as high voltages, depending on the application and interpretation of the segregated bus. Therefore, the proper answer appears to be "it depends on circumstances."
