Difference between 200A & 600A Loadbreak elbows (or) What does 200A/ 600A mean for a Loadbreak e
(OP)
Hello all,
Does anyone has an idea about 200A & 600A loadbreak elbows? I came across this while designing a pad-mounted transformer. Initially I thought that this ampere rating would be calculated from rated kVA and rated Voltage but for a 75kVA transformer with 13.2kV (L-L) on primary would lead to around 4A. Being that said, these 200A/ 600A loadbreak elbows are connected to primary (such a large rating ones)!! I am confused! I am not sure whether I am approaching in a correct way or not. Can anyone get me out this tangle situation.
Thank you in advance,
Rohit

I appreciate your comment but on what factor do we select 200A/ 600A elbows? Does that depend on primary full load current or secondary full load current of a transformer?

As already mentioned, the 600A are not load break. Load break means a suitably trained high voltage electrician can use a hot stick to pull out the elbow and disconnect the transformer. The elbow with its exposed live conductor inside would then be plugged into a dead end "parking" bushing to make it safe.
Load break elbows are a cheap way of doing manual switching in distribution systems.
#16 wire is good for a lot more than 4 amps. But we wouldn't run #16 to that transformer.
