Re: [RE-wrenches] current carrying conductor

Marco: From the code: Nonlinear Load. A load where the wave shape of the steady-state current does not follow the wave shape of the applied voltage. FPN: Electronic equipment, electronic/electric-discharge lighting, adjustable-speed drive systems, and similar equipment may be nonlinear loads.

Re: [RE-wrenches] current carrying conductor

How about some clear definitions-for-dummies of 1) linear loads and 2) non-linear loads? marco Marco: Will non-linear loads be expected? If so, the neutral is considered to be a current carrying conductor and needs to be counted. If no non-linear loads, then the neutral is not counted.

Re: [RE-wrenches] current carrying conductor

Marco, Take a look at 2008 NEC 310.15(4)(a).  The neutral conductor isn't counted for the purpose of NEC 310.15(B)(2)(a) when it is part of a circuit where it only carries the unbalanced current. Kent Osterberg Blue Mountain Solar Marco Mangelsdorf wrote: Thanks for se

Re: [RE-wrenches] current carrying conductor

'Neutral Conductor' is defined in article 100 as being "intended to carry current under normal conditions" so that's basically NEC defined as current carrying. You are already allowed to undersize the neutral conductor in a 3 phase system, so I think that's all the allowance you're going to get.

[RE-wrenches] current carrying conductor

Thanks for sending that link, William. OK.let's try it from a different perspective. When you're running, say, three three-phase hot conductors from point A to point B with a neutral conductor, should that neutral be considered "current carrying" from the perspective of more than three "cur

Re: [RE-wrenches] current carrying conductor

Marco: You have opened a can of worms. I hope you are happy! Are you looking for the legal definition or to discover if the neutral conductor actually carries current? The answer to the legal definition is in 310.15(B)4 (2002), and the answer is: It depends (on the type of service). This

Marco, When you are drawing 120 VAC, the neutral is a current carrying conductor. David David Katz Chief Technical Officer AEE Solar 1155 Redway Drive P.O. Box 339 Redway, CA 95560 Tel (707) 825-1200 Fax (707) 825-1202 dk...@aeesolar.com www.aeesolar.com

Marco, Seems to me he's right. It carries the net current difference between L1 and L2 from the transformer to the loads. But not having any EE training, I'm willing to learn better. Allan

[RE-wrenches] current carrying conductor

I have a disbelieving business partner who believes that the neutral conductor in a standard 120/240VAC service is a current carrying conductor. Could someone please disabuse him of that notion? Thanks, marco ___ List sponsored by Home Power
