coiled cables are a
hazard

Power Cables

In the interests of safety and/or rapid fault-finding/fixing, ALL power cables (extension cords) must be:

fully uncoiled
coiled cables can overheat, posing fire and/or 'foot-tripping' hazards

heavy duty
If you want power supplied to you, then you'll need at least a 1.0mm commercial grade or, better yet, a 1.5mm light industrial grade cable

They're both readily available from many suppliers, in a variety of gig-friendly lengths (20m or more)

Get one!!!


The Proper Way To Coil A Cable Lesson
youtube.com/watch?v=lLwwB29uQRg
Learn how to coil a cable correctly

If you want to extend the life of a power cable and prevent it turning into a spirally, tangled mess that looks as though it belongs on an old telephone receiver, then do NOT coil your cable like it's a rope

Check out the You Tube video

It demonstrates a (fairly) simple technique that's variously known as 'over-and-under', 'French' and/or 'alternating' coiling

Whatever you call it, it works!
Got a cable that already looks a mess?

Try laying it out in the sun on a hot day (on a black asphalt tennis court is ideal) and then, when it's warm, coil it the correct way - applying a bit of force if necessary
No 'domestic' cables

It's a false economy using 'domestic' grade cables.
Sure, they might be a bit cheaper to buy, but usually they are far too short to reach all the way from your stall to the nearest distro-box, often 15m or more

Also, they're not designed for the loads and stresses of repeated use at outdoor gigs

Before long, they'll get damaged and then end up in the landfill

Not exactly in keeping with the 'towards zero waste' philosophy

clearly identifiable
labels at both (the male and the female) ends
a hand-written label using a vivid marker pen on a bit of masking tape or duct tape is OK
rcd
portable RCD
fitted with a 30mA circuit breaker
Surges often occur simply as a result of switching on (or off !) high-powered equipment such as coffee machines, kettles, microwave ovens, etc

With your own in-line circuit breaker (a portable RCD and/or a surge protector multiboard) fitted at the 'business end' of your power supply (i.e. at your stall), not only will you save time (no need to traipse all the way to the distribution box to reset a circuit breaker) you'll also further minimise the risk of
  1. electrocuting yourself and/or your customers
  2. tripping out the power supply to other stalls

Working Lights

From sunset onwards, lighting can (does!) help make stalls look much more 'professional'

From dusk onwards, lighting is essential

Candles are NOT an option

Clip-on bedside lamps are very easy to rig/point, cheap to buy ($24.99 at Briscoes, even cheaper if you can find them at the Reuse/Recycle centre, aka Mitre 11) and - with energy saver bulbs - fit hand-in-glove with the Working Towards Zero Waste initiative



Electrical Warrants of Fitness

All catering vehicles that "contain a connectable installation" (e.g. carts, caravans, buses, etc - including those equipped with their own generators) must display a current electrical WOF

legislation.govt.nz - Electricity (Safety) Regulations 2010

Connectable installations

76 No supply without warrant of electrical fitness

  1. Before permitting or authorising a connection for the supply of electricity to a connectable installation in a vehicle, relocatable building, or pleasure vessel, the person supplying electricity must verify that the connectable installation has a current warrant of electrical fitness.
  2. A person who supplies electricity commits a grade B offence if he or she fails to comply with subclause (1).

Colour coding of wires for flexible cords (Single Phase)

The colour coding of the wires for NEW flexible cords will be:

Brown
Active (Phase), symbol A, P or L
