Outside lights

[fatgreeny09]

Hi, I've put some under ground lights in a restaurant with outside seating. The lights are in the ground but there is a kirb all the way around then some shale then a wall. I have come from armoured cable into a weather proof box. into a light sensor. then into a galvonised t box. this first t box is in the shale along with the rest of the wiring. from the t box with stuffing gland which goes to a ground light with flex which is fixed to the ground light. then also from the t box to another t box with armoured and then continues in the same pattern. Each t box has gasket and lid and is also filled with electricians silicone giving it ip68 compliance. I know there is a hundred opions about other ways it can be done BUT is there anything wrong with this way as this is the way I was taught and I don't believe it goes against any regs ? reason being is some other company has gone in and told them they need it all ripping out as it wrong

What is to stop anyone penetrating the cables buried in the shale? Any pics? What voltage are the lights. How are the lights fixed in the ground???? Flex doesnt sound too good in public place and presumably buried?? Must say there are a lot of questions on this one, from what you say it does not sound safe but hard to tell. Oh yea what is shale.

There is shale over the cables. the flex comes supplied with the light so there is no way to terminate the armoured to it. and they are 100% ground lights. but in short they won't walked over nor dug out.. they are 230v and may have a pic il have a look. the lights are placed in the ground with shale around. where they are place is raised by about 3 inch.

There placed in the drainage gulley to the right of the picture?
Block paving slopes from left to right of the picture, towards the gulley that was or is now filled with shale and lights.
Or are the lights now in the block paving?

Shale is a small whale.

builder built the Gulley purposely for the lights

Also the shale has been put back everywhere else. the lights are also at the back and left hand side

Sorry to say, but to me it's just a hard surface to grind up the cable. The combination of concrete base, flex, shale and pedestrian traffic doesn't seem like a good idea?

There is a walk way at the bottom of the pic where the cones are for pedestrians to walk but how would you have terminated them as they come fixed with flex if you don't mind me asking?

For me the problem is that the flex cables are hidden but not protected in the current design. Maybe I'm wrong?

What type of flex is it, rubber or pvc.

That's what the other person said but I really can't see what else can be done as it supplied with that.
