electrical question 30amp for 60amp (furnace, sofa, heater, convert)

[willc86]

first I apologize if this is the wrong section

I am hoping someone knows a bit of electrical

so, what would be more idea to feed a shed (going into a sub panel inside shed that is 70 feet away from the house)

double pole 30amp
or
60 amp double pole

i dont plan to run much stuff in the shed; maybe a tool here and there. security cameras, battery chargers
and maybe a small TV. tools would be like circular saws and stuff.

i really dooo like the price of going 10-3 wire and feeding a 60amp subpanel in the shed

just want some opinions

The wire is not the major cost in a proper job. The conduit, panel, and trenching costs make wire cost a minor factor.

The items you list are not a problem. If you want an electric space heater or two, or want to try a little welding, you might have a problem.

10-3 wire is way too small for 60 amps. For a run of 70', you may want to upsize one size to keep voltage drop to a minimum.
There are many different wire types that have different amp ratings, but most use the 60 degree C rating for sizing. If you use aluminum wire, you have to go up one size.
Also you say 10-3. Hopefully you are talking 10-3 with ground wire. You want to have two hots, one neutral, and one ground conductor to your sub panel.

#10 for 30 amps max, but you would have to use #4 for 60 amps. 30 amps would likely do everything you want.
If it was me, I would use #8 wire and 30 amp sub panel.

so im using 60amp double pole with 6/3 wire UF-B to feed a 60amp sub panel detached,

I dont think a number 4 wire is rated for 60 amps - or I can go 50 amp with 6/3 wire

You need to pull FOUR CONDUCTORS because this is a SUB PANEL.
Black Red White and Ground.

If you can get it then use it. It'll be fine to feed a 60A sub.
While you're at it use CONDUIT too not the UF.

thanks! 6/3 is four conductors. Usually ground is included.

im trying to find a store that has 4, but copper #6 is also rated for 60amps

but I am actually trying to think THWN #6 - with 4 conductors is better for this

any opinions?

I know I can put UF-B into conduit as well, it does not violate NEC, but heard its a pain to do

Do you seriously think you have to have all of that for a light, a circular saw, a tv, and a security camera?

Hell, why run 3phase to it and call it a day!? Dilly, Dilly!!

I have been wondering if I could get the high voltage lines run so I can install my own substation. I was unsuccessful in getting the railroad to run a spur to my house so I could feed the blast furnace and the foundry on coal, and the gas line to the house is only 1 1/2" and I would need at least a 4" gas line to use gas, so I am thinking to run an electric furnace instead. I am not sure whether to go with the basic open hearth or acidic open hearth, still studying on that. Originally I thought "Bessemer converter" but I think my neighbors might get upset if I blow the Bessemer converter late at night. You know, our lots are only 60 ft. wide.


Once I get all that going (hopefully next month) the next project is the 500 ton open die forging press.

6/3 is four conductors.

3 CCC, and 1 G.

I was going to give my two-cents, and see there is good advice here sofar. But it's clear you are asking questions about something about which you don't have a basic understanding.

Do some reading, buy a book, and take advantage of all the easy to use wire size calculators online. Without the skills to install your new circuit, you risk killing yourself or someone else.

Save money by trenching and running the conduit (don't backfill until inspection) and punching the requisite holes through your walls. Pay an electrician to hook it up. Good luck.
