As you dig into the NEC/NFPA you will notice several different spec's. They relate to time/current buildup for tripping in different environments. There are specs for Residential, Commercial, Construction use etc. With what we are doing, Residential environment with Industrial Equipment, it...

Quaffer - I agree fully except for these cases where you have lifespan concerns with equipment. As the brushes on your pumps wear and your elements age and gather crud they will draw slightly more current then their "as new" spec suggests. In my book I just use 80% for head room and to allow...

IMO the 80% limit is kinda important with resistive and electro-mechanical loads like heaters, motors etc. As the components age they can draw more amperage, shed leakage current, etc. The 20% overhead will allow for that. For control circuits I tend to cut much tighter unless I foresee...

@ders Sorry if I overwhelmed you. Coming from the entertainment/industrial automation world, I tend to reach for very robust and flexible solutions. Yes it is likely overkill; but, you will end up with components that will last a lifetime and are pretty easy to troubleshoot. If you want I...

Couple of notes: Looks like you are wanting to use automotive blade style fuses ... I would lean towards glass barrels or better yet, small DIN mount breakers (if you have the cash - look at Altech). Look into using a force coil contactor for your mains and be sure to wire its coil through an...

You could electrically and mechanically interlock your single SSR to independently power your elements. Unfortunately (2) 1500 W elements will pull 25 amps before you have even added your PID, lights, contactors, etc. Perhaps you can post some more information about what you want to...

Ran into the same problem with the pellets recently for a split batch falconers flight IPA. Halfway through the dry hopping time I peeled off just over a gallon and racked onto a pound of raspberries. ***I KNOW*** it might seem like a waste to rack a Falconers Flight IPA onto raspberries; but...

Just another idea ... Why go through the effort of tripping the GFCI when you could just put in a shunt trip breaker? My 2 cents ... Also in the vane of over kill why not put in a master forced coil that the mains runs through and drop the coil through the e-stop?

Yeah I like the MTW because it's stranded and works well if you are doing crimps, lugs, soldering, screw terminals, cage clamps ... Etc. But you won't be burned by using solid core THHN.

Any time I am doing panel wiring I go with correctly sized (for amperage) MTW/THHN ... It's much easier!

I am additionally available ...

Well, I thought I would post an update on my batch ... things have developed well after the last two weeks. The batch started at 1.053 and after 2 weeks has settled at 1.012 - two points over target. I am chalking it up to bad rest temperatures and ending up with a bit more un-fermentable...

Thats ok ... I can always hope ... I did like that show

I just finished last week my first AG BIAB. I used the enhanced double decoction and the process was very very smooth. I really enjoyed it. As you sit there and stir your first the decoction pull you can literally watch the chemistry at work - amazing. Also I have to say that by the end of...

jerk ... but thats ok, I will read this again in 3 more hours when it's funny on the west coast

Check out the Illuminated switches from Sprecher & Schuh. They have a modular line with different rated contacts and led's and that are stackable and super easy to service ... look at the D7 line. You should be able to find a local distributer in Portland quite easily!

Two things to note: In regards to extension cord sizing since you look like you will need one/two. For a 20amp circuit with a short run you are likely good on a 12/3 cable. But if you are running 50-100', nearing 20amps and plan of running your element for +5-6 hours ... do yourself the...

AH SO VERY VERY True ...

Awesome thanks for the heads up!

Well the batch has been fermenting for two days now and the washed Kolsch WLP029 is making a hell of a pungent smell throughout my garage. I had made a 2L starter that I chilled and decanted; and this has got to be the strongest fermentation I have seen yet. It is a 5 gal batch in a 6.5/7 gal...
