Labeling is a good idea, and probably not become a potential for an error if your station is static (you assemble it and never make a change). But someone like me that is always building/modifying/rearranging the hookups, labels (alone) will not prevent an "accident". I run my 28v power to a separate barrier terminal strip from the 12v distribution, and make it a 100% process to always measure the voltage of a new connection with a vtvm before connecting to the equipment. Same rule for making new cables (check polarity and continuity before use).
But realizing that I am "human" I used distinctly different connectors for running HV and other level voltages. Never use a RF connector for dc. So my 3.6 kV PS cannot physically be connected to the wrong connector (they look like BNC but are MHV and will not mate). Lots of caveats in construction philosophy! Another thing I am doing these days is making connection diagrams and schematics for everything. I keep them in a master drawing 3-ring notebook so always handy for a moments reference if I have a senior moment and do not recall exactly how it is supposed to go. Very handy in troubleshooting when stuff doesn't work. I operate 16-bands 600m-3cm, 17-antennas, three towers, and one dish (If I have counted correctly). I have 26 coax connections to outside the shack. Keeping track is not trivial ;-) 73, Ed - KL7UW ------------------------------ Message: 37 Date: Mon, 28 Jun 2010 10:48:20 -0500 From: Grant Youngman <[email protected]> Subject: Re: [Elecraft] Power Poles...

The other point was -- How hard is it to build a power pole connector, put it together properly, and LABEL the darn thing to avoid disasters like plugging a 24v supply into a 12v radio? :-) Grant/NQ5T 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-600w, 432-100w, 1296-60w, 3400-fall 2010 DUBUS Magazine USA Rep [email protected] ====================================== ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
