Springtime for ubilicals and tubeheads

Bill Beard used 8 pin Speakons for umbilicals. These are presumably
rated 250v for domestic as well as industrial.
The Speakon 8 way type NL8MPR is indeed rated at 250VAC.
However, it may *not* be used as a a mains connector.
Presuming it was OK for 250VDC would that he enough for you?
That's going back a few
years. Neutrik has downgraded all its 250v rating for XLRs to 50v in
latest literature - presumably this is domestic?´
Many companies have done the same. The old round Bulgin connector
used widely as a mains on prof audio equipment is now rated at only 50V.
However, it may be used at higher voltage as an interconnect within the
chassis (industrial)
Same plugs of course -
data sheet still says 250v and their salesman confirms it. I'd be
looking at up to 350v, so may be on dodgy ground here.
The connector I quoted you is OK to 7.5A at 380V IIRC.
No free lunches.
Indeed no. You need to get a copy of the manufacturer's CE
declaration to be on really safe ground.
I'm OK with the filaments in the D connectors, but still need to look
at the B+ situation. Length of lead is interesting - never thought of
that. Loads of new regs coming in it seems.
These are mainly covered in the CE markings directives. But it is
very complex indeed. They refer to low voltage as 1500V !!
