protection at swimming pool?
Brendan Welch
My daughter wants to use an audio-visual cart at a swimming pool.
The wall socket at the pool has a GFI. The cart has its own dedicated
extension cord; i.e., the female end is not loose like an
off-the-shelf cord. The cart has 110 VAC sockets. She will use
these sockets for a CD player, and for an amplifier which feeds an
underwater speaker (plus a regular in-air speaker) for water ballet
swimmers.
What is the best and legal protection? I suggest just replacing
the 110 VAC sockets of the cart with GFI ones. But she is worried
that if any accident happens, no matter how innocent, the hurt party
could sue her, me, or the YMCA which runs the pool.
Does anyone make such carts with their own GFI's?
Is it required that an electrician be the one who inserts a GFI?
Any other suggestions?
Any interpretations of the National Electric Code?

I cannot answer your question directly, but would suggest that a
properly installed, and regularly tested system (not cart) is called
for.

Those underwater speakers, cart dropping to swimming at some
accident or water getting to equipment sound like the biggest risks.
For safest setup if possible I would think woudl be first
to divide the system to two parts. First is the sound source
(CD players etc...) and the PA playing to air. If possible
those should be places as far as possible from swimming pool
(preferably permanently installed and not in cart). Those
are the mains powered equipment that should not touch water.
Use proper GFCI protection here.
The underwater speakers are another story, and with those
you should be very very careful that you can't get in any
accident dangerous electricity to the swimming pool.
I would think that some low voltage battery powered
amplifier system that get's the sound from mains system
wirelessly woudl be safest bet to avoid possible dangers.
But those are just my thoughts, I don't know the specific
regulations related to the swimming polls, so this is just
wild quessing.

No.
