Re: Electrical breaker box and wiring question

Just an idea, and I have no idea if it would work, but I am thinking that # 6 wire would be quite expensive.<br /><br />Please correct me if this is wrong, as I have thought about doing this for my fathers barn.<br /><br />Couldnt you just run two or three #12 wires, all off seperate breakers?<br /><br />Then join them together at the trailer.<br /><br />Ken

That wouldnt work,aspecially with the voltage drop on the #12...<br /><br />Although on some things you can cut corners,I wouldnt do it on electrical...

Not the same book,the one I suggested is "CODE"<br />All the advances in code change start in BC<br />The "Electrical Code Similified" book was written by the man that taught my Uncle the trade he has one for almost every province,cheap and very,very good.They usually stick them in the electrical dept and not where they have all the other rookie books,they are a fast seller

Nope, mostly because it wouldn't meet code. But a novel idea that theoretically would work, but I'm not sure there'd be any savings either because you'd need four #12 wires to equal the current carrying capacity of a single #6 wire.<br /><br />Here's why: Diameter of #6 wire is 0.1620 inches, which is almost exactly double the diameter of #12 wire which is 0.0808 inches. High school geometry taught us that the area of a circle equals pi x radius squared.<br /><br />So for easy math lets say we have a wire with a radius of 1. 1 x 1 x 3.14159 = 3.14159.<br /><br />Then we have a wire with a radius twice as large, or 2. 2 x 2 x 3.14159 = 12.5664.<br /><br />12.5664 divided by 3.14159 = 4.<br /><br />Therefore it would take four separate #12 wires to give an equal volume of conductor material to that which is found in one #6 wire.<br /><br />How's THAT for boring the bajeepers outta everyone!?

Re: Electrical breaker box and wiring question

heyttown: Yes, I will definitely keep you guys informed about how the project is going. I appreciate your input on this topic. <br /><br />Dolluper: I will check that book out in electrical tomorrow morning, and will buy it, if it is in stock. <br /><br />I'll also post any important info related to this, once I talk to the guys at HD.<br /><br />Maybe once I get the "Electrical Code Simplified" book, and my friend sees it, he might have a better clue about this as well. :rolleyes: :D

The Ont. code requires a minimum of #6 NMWU [copper] for underground "OVER 80 FEET" so BC might want #4. You could call a BC electricial inspector for advise [not from your home phone] they will be glad to help

Re: Electrical breaker box and wiring question

Guys, Keep in mind that this is a "Travel Trailer" Sometimes they do not require much for its electrical service. Some campgrounds have diffent supplies available. Ones in my area only offer 120 volt with 30 amp service.<br /><br />I don't do much with RV's, but I know what some of the service is at the sights. <br /><br />BC needs to get the specs off the appliances to get a more accurate current draw to determine how much he does need. (mostly watts for the water heater)Then also, does his main panel going to have the ampacity to handle the extra load?<br /><br />As usual it is hard to give hard facts on what he needs not knowing all the variables. He could end up having a service that is overkill or not big enough.

Re: Electrical breaker box and wiring question

I went and bought the book :Electrical Code Simplified". <br />Now it is just a matter of reading it, front to back, and then calculating what kind of wattage I am going to be using. <br />I also checked out some of the pricing for the wiring. :eek: :eek: But if this is what I need, I will have to splurge and buy it. <br />As for talking to the guys at HD, everyone was too busy today to talk. I will have to wait to talk to them until Saturday. <br />I have to read the book first anyways. <br />B.C.

Re: Electrical breaker box and wiring question

I fell better now you have a real book,at least it will be done by "CODE"
