All the wires go to the gate control box on the back of the gate pillar. From there, will be a trench to contain the SWA and a two-wire 1.5mm2 or 2.5mm2 12v cable for the EntryVue video intercom bus. This goes to an existing wired box outside the house put there for this purpose.

The two slabs are already done, nearly a tonne of concrete each, with steel i-beams for cores sticking up. And the brick pillars, when built, have to be filled with concrete, too, so they can't be hollow. So ducting is a nice idea, it's just that I think I would need four (two lights...

It's ok, it would be only from the front of the pillar, somewhere near the top, to the back of the pillar, somewhere near the bottom, with a slight bend around the steel core. Less than 2m, I would think.

The photocells use 6-core alarm cable so no problem there. I was going to use a 20mm flexible corrugated conduit just for the intercom/door entry which is two cables. Thing is, if I use a conduit for the photocell, a conduit for the intercom, two conduits for the two lights (one at front, one...

Thanks bernard, ducts is a good answer. Does the type of earthing depend on the distance? It's 37m Yes, there will be electric motors and the gate company will install those. I just wanted to get wires in now to avoid trying to drill through the pillars later, as they have large steel i-beams...

When I built my house four years ago, I asked the electrician to include an outside box on a separate circuit breaker so that later I could run 2.5mm2 SWA for electric gates/lights. I'm about to build the brick pillars on the drive and I want to bury wires inside the pillars, for a couple of...
