Is that exatly what his book says? An ungrounded 240 volt system requires the use of a straight rated breaker, but corner grounded and high leg systems also require the use of a straight rated breaker. In addition, there is no rule that says you can't use a straight rated breaker on a 120/240 volt single phase grounded system.he states that straight breaker means system is ungrounded
