Give the guy a break. He's 15 and getting started.
There is absolutely nothing wrong with 'domestic grade' extensions, especially the surge protected ones. They will be PA tested I expect.
Plus they'll probably be using the same domestic grade electricity in the venue as in the housing estate down the road.
Don't understand the 'mad' smilie, I'm sure.
I'll try to offer a simple answer in one post:
Fuses don't wear out with use. However, if a fuse is run at or slightly over its rated current, it will fail eventually due to degradation of the conductor as it could be running near red-hot, depending on how close to the limit the current actually is. Moot point though, as this merely indicates you have the wrong fuse installed.
There is no simple way to measure how heat damaged a fuse is, so forget that.
If a fuse does blow, it usually indicates a fault somewhere, so simply replacing it may simply result in another blown fuse.
You could make a little tester out of a battery, an LED and a bit of wire - this would quickly tell you whether the fuse was OK or not.
I've just been asked by a hotel do i have RCD's, told them they are surge protected....she seems OK about that......never run the cables through RCD's before.... ........as said all leads are surge....but not RCD's.
Does it get bulky at the mains point?...i imagine they are chunky bits so therefore taking up more room.....
...thoughts....
Uh..."You have been fined 99 bicycle clips, go directly to jail, do not collect 200 pounds... who's that naughty boy there?"
I don’t want to go off subject but an RCD doesn’t stop a surge.
An RCD works by “monitoring” the live and neutral, if there is an imbalance of more than 30mA it will “trip”.
An imbalance will happen if the wire is cut or if there is a problem with the equipment and power is going to “earth”.
A surge protector is a different thing; these are normally incorporated in special extension leads, the work by “absorbing” spikes in the electric supply.
It’s very technical; I spent four years getting to grips with it!
Hope it makes some sense
