That's funny... my table shows 20A for #12... Edit: OK... I see what you're saying on column "B"...)

You go by the temperature rating of your teminals... that's all fine and dandy that the spool spells out 90degrees and so does thhn/thwn for that manner BUT you go by the temperature rating of the terminals which will be 75 degrees so that is the column you go by. Ultimately you can do whatever...

I did read the thread and that is why I confirmed the wire sizes and overcurrent protection required for the wires. There is no exception for control panels in the code and I think this thread is very misleading.

If they didn't apply there would be an exception in the NEC... please point it out.

Yeah... just saying but the overcurrent protection for #14 thhn/thwn is 15amps, #12 is 20amps and #10 is 30amps... I don't care what kind of philosophical spin you put on it. If the terminals are rated for 75 degrees (which most all are) then you use the 75 degree column.

Typical #12 THHN/THWN is good for 600V; it's the amps you need to be concerned with... Overcurrent protection for #14 should be 15amps; #12 20amps; #10 30amps.

I just priced my last purchase from the Local Shop against Morebeer which has free shipping and could have saved 25bucks getting it from Morebeer PLUS I wouldn't have to try and hit the during the week hours of 10am to 6pm (I work for a living and traffic trying to get there after work by six is...

Agreed sfrisby... I would support locally more too if the one or two around me just had a decent website... at LEAST showing all products in stock... I work for a living and to try and make it to one of the few stores during their hours of operation to hopefully find what I'm looking for is...

....ok... I moved my name to the waiting list tab.... I'm ready for the base malts... All components of my control panel will be here Tuesday...

What do you mean it ain't pretty? For two hundred bucks I think that's the most beautiful thing that I've ever seen.... Nice!

I'd get a volt meter and test black to ground, white to ground, and black to white.... When you say two 30amp breakers... do they have a common handle?

I agree Bobby... I don't see the point in relying on a breaker to trip if both loads are on at the same time.

I was going to say a 30amp double pole double throw disconnect was your only option but the P&S 1276 30A double pole double throw manual contoller may work... http://www.gordonelectricsupply.com/index~text~5600547~path~product~part~5600547~ds~dept~process~search

It's only rated at 10amps at 250V so no... that will definitely not cut it.

I would just install a weatherproof loadcenter outside at the end of the run and then you could do whatever you wanted. Leave the 50A 2Pole breaker inside and roll with it, take the conduit loose at the last fitting, pull the conduit off the wire, cut to desired length, put back on wire, get a...

I'm in Suwanee and work in Alpharetta....

Very cool... I used to brew about twenty years ago prior to marriage.... seeing as I'm single again I'll be brewing again :D and I'm currently working on the new rig and hope to be up and running by Christmas doing 12 gallon batches... I put in an order for two sacks but may add to it once I...

NICE! I'm waiting on my panel DIY kit now.... In the meantime I'm working on my kettles, pumps and wort chiller and am far as I can go until I get the HERMS coil and probes on Wednesday and Control Panel Kit. Last night I was using my pumps with a foot switch testing for leaks... :D Can't...
