Local colloquialism in consultant's drawings

[MacG]

Greetings All,

I see the phrase "All circuits shall have dedicated grounded (IE. no common "round-house neutral") conductors and installed equipment ground." on a bid set/not for construction set of drawings. What is a common "round-house neutral"? Since Google did not help I figured some you guys might have runs across this locally. I suspect this is another way of saying do not use self grounding outlet devices and only use isolated ground outlet devices but I could be wrong. It is just that I have never heard that term before and thought I would ask a not dumb question

Thanks for your input,

Context clues suggest round-house = shared neutral of a multi wire branch circuit.

Round house =Three hots and one neutral.

Designer does not want you to use multwire branch circuits.

You need to pull a neutral for every ungrounded conductor on 120 and/or 277 volt circuit.

Roundhouse, full boat, round robin, are three that come to mind all mean multiwire branch circuit. any more I am forgetting?

Of those, the only one I had heard before was full boat. However, as a design engineer, I would never put a slang phrase on an official drawing.

I've kicked several sets of plans back to the architect/designer for having improper terminology. Nice to see someone out there takes their job seriously. :thumbsup:

Around here we use the term full set. If you were running out some homeruns in conduit you might pull in three full sets or nine circuits.

Thank you!
