Discussion on group IV papers [(a) oil switches, (b) spark gap. (c) wave form. (d) regulation]. New York, February 28, 1913. (see proceedings for February, 1913)

Paul M. Lincoln: The paper of Mr. Burnham´s on oil circuit breakers opens up an interesting subject. The question on the method of rating an oil circuit breaker is an important one, and is one upon which the Standards Committee, I believe, should take some action. I am prepared to accept most of the suggestions made in Mr. Burnham´s paper. It is necessary to rate circuit breakers in various ways; one way to rate them is in regard to their current carrying capacity, and they must have such a rating. They must also have a voltage rating to indicate the maximum voltage of the circuit upon which they may be used.
