May I recommend PowerPole connectors and frequent use of diode-OR. For 
details see:

http://leapsecond.com/pages/powerpole/diode-or.htm

I got the inspiration when my Dad was in the hospital and I saw how they 
did IV tubes with multiple injection points. It seemed so simple, 
clever, reliable. Details [1] and graphic photo [2].

So now I use diode-OR "Y" connectors on all my long-term standards. It 
allows me to replace either power supply live without interruption at 
any time. Come to think of it, they call it an IV in the hospital. And 
here in my lab the I is about 0.18 and V is 24 so my IV is 4 watts. ;-)
