underground lighting cables

[sonobit]

hi just some quick advice please guys, im working on a lampost circuit and the lamposts have been half buried so the inspection cover is underground, ive dug around one removed the cover and there is no fuse for the light, can I terminate the SWA cables in a steel box and put a IP68 plastic box inside of this and fuse the live then put the whole box just below the surface under the flag stone? or is there a better way cheers guys!

you can terminate the SWA in a plastic box as long as you banjo and fly lead the glands.

yeah i was thinking that, but was thinking the metal box would provide mechanical protection also, is it ok to put the fused live under the flag just like that then?

Lamposts have a colour scheme on the actual post...the bottom 12inchs is normally a light grey - it's the point that should be flush with the ground. The inspection panel shouldn't be underground. Im guessing they must be old lamposts....

Thats the sort of thing you should really be terminating into...a lampost connection unit. That's if you can dig far enough to work comfortably.

Failing that then yeah you're going to have do it the way you said in a buried IP rated box...not ideal really imo, but what can you do...

Is putting the box with the fuse and everything in just under the flagstone still classed as accessible if the fuse blows, or will i nee to put it all in some kind of inspection pit like an earth rod pit?

Obviously that scenario would be MORE accessible im just asking if its STILL classed as accessible? also is there a better kind of inspection box OTHER than an earth rod pit?

Well who was the clever bugger that mounted the posts so that the access cover is part underground?? All i can say, is be prepared for excessive corrosion and condensation inside that lamp post. ...Plump crazy!! lol!!

is the lampost cast in concrete or is it in a sleeve/large pipe thats cast in concrete

 

[sonobit]

its cast straight into concrete
