Link Posted: Sat Sep 03, 2022 11:22 pm Post subject: Browned Control Panel Cable Locking Connector - Need Help |
|
|
Cause for concern? Brewed 27th electric brew today, Saturday, September 3, 2022 since building my electric brewery. When I was cleaning up, unplugging the 240V connector plug from the control panel (240V power in) was difficult. Normally, it’s an easy twist and pull. I finally managed to unplug the 240V connector plug from the control panel. Curious, I looked at the connector plug end and notice what appears as browning (burning?) mark.
Unsure if this happened today or during another brew session. Opening the control panel (yes, the control panel is now unplugged from the 240V wall receptable), I didn’t smell anything burning, no plastic burning smell, etc.
Checked the 240V receptacle (240V power in) inside the control panel. All wires are tight. Nothing loose. The browned outlet area in the cable connector plug connects to the black wire in the control panel receptacle.
I did notice in the control panel receptacle spade (maybe this isn’t the correct word to describe?) for the white control panel receptacle wiggles. Is this normal?
Is there cause for concern?
Is my Leviton 2713 30 Amp, 125/250 Volt, NEMA L14-30R, 3P, 4W, Locking Connector, Industrial Grade, Grounding - Black-White bad?
Is my Leviton 2715 30-Amp, 125/250 Volt, Flanged Inlet Locking Receptacle, Industrial Grade, Grounding, White bad?

What about the 240V power in white wire spade wiggle?
I've been thinking a LOT about this since I posted. Possible this happened when I got distracted and mistakenly plugged in the HLT to the Brew Kettle heating element and the Brew Kettle heating element to the HLT control? This was about a year ago. No, wasn't drinking any homebrew at the time as I never have any while brewing. Got distracted, wasn't paying proper attention and mis-connected things. I've taken measure to ensure this NEVER happens again.
Brew Kettle heating element got cherry red (without liquid in the brew kettle) before I noticed and killed power to the control panel.

All connections should always be solid. There should not be any loose connections. See the link I posted above for more.

By "spade" I'm writing about the male copper part of the "Leviton 2715 30-Amp, 125/250 Volt, Flanged Inlet Locking Receptacle, Industrial Grade, Grounding, White" control panel 240V power in receptacle. Not the wire going to the receptacle, the copper/brass part (what I'm calling the "spade" visible from underneath the control panel).
All connections on both the plug locking receptacle and the control panel (power in) receptacle are "solid".

What about me mistakenly using the brew kettle heating element? Could this mistake have caused?

If a plug is dirty or not properly locked into a receptacle similar things can happen.

Your picture shows a receptacle that is charred, so it can't be "solid". If it was solid, you wouldn't have charring. See the previous link I posted. There are many reasons why this can happen when a connection is done incorrectly. It could be something as simple as mistakenly cutting some of the wire strands which effectively reduces the wire gauge, causing excess heat. There are other possible reasons too. Give the link I provided recently a read as it explains possible reasons:

We see this often when people build their own stuff.

I think you mean firing an element dry? That won't cause a plug or receptacle to char or discolour up the chain.

In your first post you have a picture of a female locking connector called "Cable Locking Connector.jpg" that looks like it's part of a power cord. What is that exactly? Just curious as female locking connectors outside of the control panel are not used in the design documented on our website. So not really sure what you've done. The more information the better.

??? These are from your 2014 Edition The Complete Guide to Building Your Brewery. The cable locking connector is shown on page 251 of the guide. The link goes to

Sorry, you were talking about heating elements (completely unrelated) so I thought maybe you had done something different with your heating element cables.
As mentioned above the charring is from a poor connection. See the previous link for a list of the most common reasons.
Good luck!

Checked the control panel and discovered several loose screws/wires/connections due to heating/cooling. Seems to me the build should mention the use of "LocTite" or something similar to prevent from happening or is this the secret "ingredient" in the purchased build?

liquid threadlockers shouldn’t be used here. Make sure your connections are tight. For our pre-assembled panels that may travel thousands of miles we do have some warnings when you first open the box which recommend retightening some of the high current connections to ensure that they have not loosened due to excessive vibration during shipping. For kits this should not be required.
