power cable protection across venue

Postby hooty2 » Sat Sep 08, 2018 12:05 pm

Hello,
i'm looking for advice on correctly specified cable protection for a 13amp power cable that runs from a wall socket out to an electrical piano across a stone floor in a cathedral.
we have a big number of students on metal chairs in-between the piano and the wall socket!
there are a wealth of products on-line and i have been looking up electrical safety in public venues etc.
I am the recording guy and not directly involved in this aspect of the gig but i have identified the issue and suggested that the simple thin rubber matting being used is not safe and may be illegal.
i intend taking my own correct cable protection to the next event and also suggest (sort of quite strongly) that the venue, in making the electric piano available and accepting the hire...should have addressed this.
Maybe i'm out of order and i stand to be corrected.
Saving face is not my concern here, saving lives is!
any guidance welcomed

The cable really be should be run round the edges and away from public seating areas to avoid any chance of a chair leg resting on the cable. You may need a longer power cable to do so, but it's worth it. Apart from that, the main risk of a cable is as a trip hazard. Mats themselves can be trip hazards if they curl up at the edges (so would need taping down), and the mat itself may disguise the fact that there's a cable underneath it if it's dark and non-reflective, so people can still get caught out by it if treading on something that's a bit higher than they were expecting.

Thanks for that Wonks.
I did suggest that routing but they baulked at crossing the footway twice.
The main issue from their perspective was the number of children on chairs..and oddly complaining about their own cable to piano.
Don't get me wrong, they are hard working and mostly accommodating,
And we have mostly a good rapport, if at times a bit ambiguous.
My own mats are tediously heavy and hazard taped, and taped if curling at edges etc

It is possible to get rubber cable protectors that are clearly identified and quite broad and heavy - they may be a bit pricey for a one-off job.
I found this on a simple search.

P.S.
Would you please NOT reply while I'm still composing mine! :lol:

Just because you know what I'm talking about, it doesn't mean I do!

Mr F's cable protectors are a very good option. However, I'm with wonks on this: the cable should be routed around the walls, away from the seating, and then across to the piano by the shortest route via a protector.

No cables should ever cross a doorway on the floor. Always go up and over...
