Well, you could always try Radcom! The March issue (arriving any day
now) winds up a three-part series on exactly this topic.
Unfortunately the articles are only accessible to RSGB members, but
there are further links at the 'In Practice' URL below, including a link
to Mark K5AM.
I strongly agree with Rick K2XT about using the same multi-way connector
for ground, B-minus and the control line that energizes the HV mains
relay. This ensures that HV cannot appear unless the supply also has its
B-minus and safety ground returns.
For remote HV supplies I am *strongly* recommending coaxial HV
connectors which again guarantee a safety ground.
