How much/what electrical danger performing on a covered stage during rain?

[ChairmanOfTheBored]

These are what professionals use

Lame. And you apparently do not know what the word professional means
either.

 

[ChairmanOfTheBored]

It takes a lot less than that - .05A across the heart can kill you,
and .1A across the heart will most likely cause destructive ventricular
fibrillation.

Open heart surgery, defibrillator paddles are 2" in diameter and
operate at 2mA.

"bits of kit"

Get some language in your life, retard.

No, sorry chump. Rugged gear does not EVER look like it is made
overseas.

What a sorry bit of kit god gave you for a brain.

yep, couldn't even find a spec for them, not even an IP number for
splash resistance, and a brief look at their brochure, well, even
Eeyore could pull that apart.

And no obvious mention of certification, from anything US or EU based

They seem like piles of junk.
I couldn't even find a frequency reponse, for the audio side, let
alone the RF side

Get a job at a bank.....or as a scientologist, they both need
criminals

Actually RCDs are available with tripping currents of 10, 30, 100 & 300mA
and in time delayed versions. That's only from the MK "Sentry" catalogue -
there are probably others available as well.

** Try reading the whole story.

MK state clearly that ONLY the 30mA models are capable of giving good
shock protection.

The 100 mA models are ONLY intended where a 30 mA one cannot be used -
presumably because inherent circuit leakage to ground equals or exceeds
30mA.

MK also state the a 300mA model is PURELY intended for equipment and fire
protection.

From the point of view of UK wiring regs, RCDs used for protection
against electrocution must be rated at no more than 30mA (and this
is similar in many other countries wiring codes too).
RCDs for protection against high earth fault loop impedance and
not electrocution should be rated at least 100mA. 300mA and 500mA
are common values too.

10mA RCDs as mentioned above are available but are rare. They are
used for protection against electrocution in restrictive conductive
locations (where someone may not be able to remove themselves from
contact with faulty live part due to working in a location which
restricts movement, such as maintenance work inside a pipeline).
10mA RCDs are also suitable for single appliances, but generally
not suitable for circuits feeding many appliances, particularly
Class I IT equipment.

The mysterious phrase " high earth fault loop impedance " don't mean jack
shit to anyone.

The use of plain language is always preferred when addressing an audience.

You're the fucking criminal, asswipe. So is your mother for not
flushing you down the toilet like she should have.

 

[David Lesher]

Yes, but now you need to get power to the mike, as well, since the fibre
can't carry it. There are plenty of systems with fibre links between
the stage box and the console;

So you use a battery in the mike->fiber converter on the performer's
belt or hide it in the middle of his back al-la GWB.

On stand-mounted mikes, ditto.

The military makes fiber that's allegely sturdy enough to survive
being driven over by a tank, so the average rock group should have to
work hard to do it in...

God, I hate doing that. That now becomes the number one major failure
source, the same way it is with wireless packs. And now you have to
replace all the batteries before every performance, just in case. Just
like wireless packs.

Yes, the military tactical fibre is very commonly used in this application,
although most folks today are using the lower cost broadcast connectors
instead of the military T-FOCA ones. The military connectors are several
hundred bucks a pop which can often exceed the cost of the cable.... some
friends at Univision recently spent $30K for only half a mile of tactical
cable and Neutrik broadcast connectors (including the cost of the sling to
carry the reels on your back). That's a whole lot more than 16-channel
Canare snake cable, but probably less than video triax bundles. And it's
a lot lighter to carry around.

True... but look at the good side; you never run out of tested batteries
for your smoke detectors & garage door openers.

If it's Elvis impersonators or similar; you could use a wobble generator
like those magnet+coil flashlights you shake to power up. I've also heard
of a larger version on railroad cars...

A FOAF founded a company that makes fiber converter systems for remote
broadcast cameras. Initially they were a hit for golf tournament
coverage. It used to be the network had to dispatch multiple
semi-trailers with honking big reels storing the miles of $$$$
copper. Now, one small diameter fiber does the job. His market has now
spread far beyond golf, I suspect.

He should go see Smith & Wesson for help. One quick treatment, and
he'll never be unhappy, again.

Nooooo, get him an account with the Bank of Scientology, let them
drain his money, then he can go to S+W.

Other options, a date with Phil from Oz, or Genome cooks him a meal
( sorry other NG',s sci.electonixs in jokes, maybe)

Make him live with Eyesore. After all, "Asses of a feather, crap

Err that is plain language, the its the minimum impedance a fault to
ground can flow through. Jack Shit will almost certainly have to high a
resistance to comply with code.
