Wiring a temp container?

[TPES]

Not that long ago I supplied power to a portacabbin, it was fed from a 3 phase panel in a close by building.

I TT'd the cabbin/site office, there is a small single phase sub board in the cabbin.

Now there is going to be 2 x metal storage containers placed next to the portacabbin for storing materials ect,

The 2 x containers want to have 1 x light & 2 x sockets in each..

My question is, is it ok to use the TT earth rod for the cabbin to earth the 2 containers? Or does each container need it's own rod? There all next to each other.

Also what wiring method would you use for this tempory install, there steel containers and will be there for around 6-8 months

Presumably you will supply the two containers from spare ways in the office portacabin in which case use the existing rod....Plastic conduit wiring system in the containers.....dont forget to bond the steel containers.

we export the earth from the supply when we wire temporary containers - we also wire in plastic conduit inside.

as a precaution against stupidity, we leave 5 meters of SWA on the roof of each container between termination points, in the hope that if someone tries to move it for any reason and we are not around, they'll see the cable before they just lift the container and rip the installation apart.

Now that is a sensible precaution

One slight doubt though,is 5 meters enough length for the idiots brain to process the message before the Doh

you obviously never worked round our end, leave 5meters of cable anywhere and itll be gone before you know it.
