TANDEM CIRCUIT BREAKERS
10,000 AIR -- One Pole Tandem
120/240 VAC (one space required).
15-20 Ampere one pole tandem
breakers are suitable for use with 60C or
75C conductors. 15-30 Ampere two pole
tandem breakers are suitable for use with
75C conductors.

I asked on another site, but since I was not an electrician, they were not able to tell me.

They are good in Michigan. Usually the panels are setup to accept the twin breakers in the lower few slots.

I just need to know if I can use them in Illinois, I guess I will see when I talk to the electrcian. Just wanted to know before then.

[Paul Seaman]

I've only heard of a few exceptions to the NEC and most of those involve conduit in a uncontrolled environment{ huricane zone}. The National Electric Code, is very complete and wide reaching. There are specifications of where thing are not proper and your application may be one but an electrician should be able to help.

Peace,

I would talk to a local electrician. What is and is not acceptable electrically is generally determined by the version of the NEC codes being used by your local governing agency. I had a copy of the 2005 codes but someone else must have needed it more.

Before you purchase your breaker make sure it matches the others in your panel. There are a couple of different makes out there and I do not believe they are all interchangeable.

MAC702 would have more knowledge here then I. I am only an apprentice card carrying member.

MAC702...where are you?

I be here. In fact, I think I'm the one (or one of the couple) that first recommended the tandem breakers. However, I have no idea what the laws in Illinois are. Fortunately, I am presently working here with a another union electrician from Chicago. I can ask him this morning and post his answer at lunchtime.

Sounds good Mac, thanks

Tommy I just need more space in my panel.

[MAC702]

He's in the same situation I was for many years. As union hands, we rarely do residential; I do quite a bit now in my own business, though.

He said he used them about 10 years ago on one job, but hasn't been around them since and doesn't know if the laws have changed to make them illegal.

I still don't see why they would be illegal Modern technology makes it possible to make a breaker smaller and fit two in the space of one. What's the big deal?

I wired my stepdad's new shop and purposely choose a 125A panel with tandem breakers for the initial installation. They weren't that much more and I'm guaranteeing myself plenty of room for the future.

[90blackcrx]

Well the only reason I heard on why there illegal, is because they heat up faster , and I guess start a fire.

I have an electrician coming in tomorrow, hopefully I don't get a price that is going to leave me poor . The job is pretty simply, only problem I fore see if not having the space in the panel. But besides that, all I want is a 240v outlet ( I'll be happy with just one ) wired about 4 feet from the panel just outside though.

[Bob Sigmon]

That's an old wives tale! If it is rated for 20 amps it is rated for 20 amps. I have a few in every panel in my house and shop and have never had a problem over many years. Just be sure to use the right amperage and wire for the situation.

[90blackcrx]

I just talked to an electrcian I called, he will be here tomorrow. Anyways he knew right away what the 240v outlet was for, he asked if it was for a welder. So that put a smile on my face, hopefully everything goes well.

[Bob Sigmon]

Congrats on finding someone that knows whats going on!

Not getting my hopes up yet, will see tomorrow and you know I will be posting in this thread about it.

[90blackcrx]

Well the guy stood me up today, 5 times to be exact. Kept calling him back and remaking appointments. Said he was waiting for a guy to sign off. Anyways he told me the tandem breakers are indeed against the law, he said he will stop by tomorrow, so I hope it shows. But it looks like we are going to have to upgrade the panel.

The guy kind of seems to, I don't know what you would call it. But 2 times he kind of lied to me, once he said he was 30 mins away, then he asked for my address, I mean how do you know how far away you are if you don't know where I live. Then he did the same thing about the price. Oh well we will see how it goes tomorrow
