Ok…Ok…in a technical way it is safety and so on…yada…yada…yada…lets see how many people get it right.

Question:
What is the minimum insulation level for neutral conductors of solidly grounded systems?

Got this from the JLC board and did not want to answer it their in order to see how many here can get it.

Ok…it is also open to Greg, Brian, Bob and Joe…gotta be fair guys…thehehe

From a practical sense 600v is going to be the answer since that is the rating of most commonly sold conductors for low voltage (<600 v).

> 1kv has this rule
250.184 Solidly Grounded Neutral Systems.
(A) Neutral Conductor. The minimum insulation level for neutral conductors of solidly grounded systems shall be 600 volts.
