Help with DIY dedicated circuit

@djones...you are very mistaken, he’s running two circuits using the same neutral. Two single pole breakers should be used, one for each circuit. A double pole breaker is designed to use different phases, all he has to do is put the single poles back in where the double pole is. I suggest you stop giving out electrical information, you are clueless.

The National Electrical Code permits multiwire branch circuits, but adds requirements to make them safer. Section 210.4(B) states that in the panelboard where the branch circuit originates, all ungrounded conductors must be provided with a means to disconnect them simultaneously. This is usually a double-pole breaker, but two single-pole breakers may be used if they have an identified handle tie.

Read your own link jea48 it clearly states to use 2 PHASES , I suggest you quit giving advice you are past clueless.

@djones51

HUH?

Is your username mental?

I suggest YOU reread my previous post. mental didn’t have any problem understanding it was directed at him.

@Jea...all you did was google nonsense that you yourself do not understand.

You cherry pick portions of the conversation, google, and act like you come up with a correct answer. You did not, all you did was create more nonsense.

Like I said, done with this silliness, but I will remember..

Yes I used Google. It beats the hell out of a lot of typing. Copy and paste... Was any of the info wrong? NO!

What NEC code edition are you using? I am using the 2017. The NEC 2008 added 210.4(B) which requires,

Disconnecting Means. Each multiwire branch circuit shall be provide with a means that will simultaneously disconnect all ungrounded conductors at the point where the branch circuit originates

Right out of the NEC 2008 book mental. Again what was the last NEC Code book you used?

You cherry pick portions of the conversation, google, and act like you come up with a correct answer. You did not, all you did was create more nonsense.

Nonsense huh? If you are going to give the OP advise on how to do his own electrical wiring you should at least give him info that meets Code. Technically, depending on the AHJ where he lives, he may not even be able to use his existing multiwire branch circuit for his application. Good chance the AHJ in his area adopted the NEC requiring AFCI protection of 120V 15 and 20 amp branch circuits that he wants to install. Also there is a very good chance Tamper Resistant receptacles are required.

In closing I would be more than happy to match wits on my knowledge of the NEC with yours.

Best regards.

Apology accepted.

Just a guess the last NEC code addition book you were using before you retired was the 1999. The NEC really started changing and adding things in the 2005 edition. Even more changes in 2008, 2011, 2014, and 2017. Probably the most changes in 2008 and 2014.

@mental,

You just won’t admit you were wrong, will you? You said djones was clueless on the subject. Turns out he was right and you were wrong. You just refuse to fess up you were wrong.
Yeah, 2 single pole breakers can be used for a multiwire branch circuit providing an approved breaker tie is used linking the two breakers together. Do you know why 210.4(B) was added to the NEC 2008 Code?

If you are going to give out free professional electrical wiring advice, ( you stated you are an electrician), on a public internet forum I suggest you get your facts straight.

Al (almarg), thank you for the kind words.
