I actually wired up the Safe Start Interlock while I was initially wiring the main power relay. I tested the circuit before anything else was wired. All switches off = main relay comes on and blue light comes on. Any of the 3 switches turned on and the panel will not power up. When the panel was already on I was able to turn on any of the 3 switches and still maintain power to the panel.
I knew I was going to go the Safe Start Interlock route from the beginning so I just wired it up that way.

you said that the output voltage on the doorbell transformer should read 120vac, i thought the output was supposed to be reduced to 12vac before it got to the dc pwr supply?

Thanks! As long as the result is more beer in the world, my job here is done. Beer makes the world a happier place.

Is there a link or sticky to a full schematic diagram for the different panels. ? Or would this be just use PJ's schematics.

There's no "one" big schematic. They've been broken down into functional sections to make it easier for people to wire that may not be familiar with wiring.
Diagrams are here:
Standard 30A panel: http://www.theelectricbrewery.com/control-panel-part-1
Standard 30A panel addendum for countries with only 240V: http://www.theelectricbrewery.com/forum/viewtopic.php?t=25393
50A 30+ gallon panel addendum: http://www.theelectricbrewery.com/forum/viewtopic.php?t=24918
50A back to back panel addendum: http://www.theelectricbrewery.com/forum/viewtopic.php?t=25793
PJ is a user over at the HomeBrewTalk.com forum that has drawn up countless of schematics for people. They're all different. I don't think he does it anymore. He's in no way affiliated with us here. I can't speak for him nor have reviewed all of his work, so I don't see how you could use any of his diagrams for our panels. For what it's worth most of his designs include the feature of purposely shunting current to ground through an emergency stop switch to turn the panel off in case of an emergency. It assumes that your GFI breaker will protect you. Even though he argues that this is fine to do, this is not a safe practice and would never pass any sort of inspection and would never be allowed in a UL panel shop. I (and many others) strongly suggest not implementing such a feature. BYO magazine published one of his designs a few years back and I and other electrical engineer made them change it before it went to print (we're on the technical review board).

There is definitely more beer at my house (and my friends houses) because of it!

Any idea why when i go to turn on the safe start relay or main contractor I trip my main ground fault breaker.. Even if i unhook everything and just have the coil hooked up I trip it.. But have no problem running a 5500w heating element directly and running for hours..
Is it the coil surge on the contractors ?

If the GFI is tripping something is not correct. It is not normal. Something has been done differently or incorrectly. It could be an incorrect part, incorrect wiring, or a defective part. It could be an incorrectly wired GFI. Unfortunately it's nearly impossible for someone to troubleshoot this for you remotely.

I rechecked all the wiring .. Replaced the ground fault with another breaker and all the functions work in the panel just fine..
I need to debug my Spa panel now.. maybe it is a faulty ground fault breaker.. eaton gfcb250 5mA sensitivity

Want to check before hooking up meters ... I also having issues with a dc power supply.. Have not hooked up the output to DC side yet.. one supply adjusts just fine.. the other I turned the pot more then 30 times Clockwise and will not go down below 13.8vdc ..

Did you source the parts yourself? If so, are you using doorbell transformers? If so, are you using the type that has variable voltage based on how you connect it? If the answers to all those questions are yes, you may want to check how the connections are and if you can re-wire them to a lower voltage on the transformer.

All parts from b2b kit ..
i will check the incoming AC to the board next.. but the transformers are identical

Yes.. bought the full B2B kit from Kal and Mike.. and a perfect kit I might add.. no issues except this one.. Took me two days to assemble.. I will put up pics later of the box it self.
BTW I am a EEE and past life designed and built industrial automation controls like this.. So knowledge is not the issue here.

Added a hint on how to run a PID without a temperature probe. This can sometimes be handy when testing a PID/SSR/heating element when a probe is not available.

Added a couple of hints that have to do specifically with SSR leakage current (these are common questions):
Quote: | The ELEMENT ON yellow light glows dimly when the ELEMENT SELECT switch is in the ON position without the element connected! Is something broken?
I'm measuring voltage at the output of the SSR even though the SSR is supposed to be off! Is it broken? |

Added a new hint:
Quote: | One of my switches works backwards! It's on when it should be off, and off when it should be on.
Switches use either NO or NC contactors (or both). Make sure to use the correct ones following our wiring guides. If you are sure the correct ones are being used, reverse the position on the switch. For example, if the switch has the correct contactor installed on the left side and the switch is working backwards, install the contactor on the right. Ignore the 1/2/3/4 numbers printed on the contactors. Contactors are not polarized (there is no in or out connection points) so it doesn't matter which side of the contactor is used when wiring.
