Browse Forums General Discussion 1 Jun 26, 2013 7:33 pm Using the "Things you forgot" checklist we've (hopefully) identified the external electrics we'll require. These requirements range from LED Lighting for the driveway, decorative lighting for the garden (front and back) through to a submerged pump in the concrete underground water tank. The LED lighting (for driveway and garden) will require 240v drivers, obviously the pump will need 240v. The question is, as we're getting close to having to detail our electrical requirements, what is the best way of actually distributing the power from the meter box to the required locations ? I'm thinking something like getting them to run two (240v) conduits from the meter box, one to the front LHS of the property, one to the rear LHS. At these locations could they install "something" that will either allow me to get an electrician in after handover to install power-points or some sort of big-box-enclosed-outside-power-points ? I might need some sort of "water-proof box" near each of these locations to house the LED drivers and timers as they obviously won't be on 24/7. Or should I have them run a 240v line to each of these locations and a "timer-switched" 240v line also ? How many power-points (total Watts) could one power cable in a conduit supply to each location ? What is the neatest way to achieve this ? Would they put the cable in conduit through the house-slab and underground the last few meters ? Many thanks, P_D .

My build has a three-phase termination point running to the back of the house on a dedicated circuit These can handle up to 20 amps per point if they are connected to a direct circuit. You might even be able to get a 32 amp circuit if your builder supports it (mine provided two spare 32-amp circuits for just such use). Depending on the location they'll either run them under the slab (typical for three-phase) or through the ceiling (more common for single-phase). You'll be able to run around 3800 watts (voltage x amps x 80%, with 80% being a common suggested load limit for the circuit) on a 20 amp circuit. A common way to run this for single-phase would be in the roof to the edge of the house, down through the frame to about a foot above ground level for a junction box, then your post-handover installer would run it down into the ground, underground to the final location, and install a waterproof cabinet to house the equipment. LED lighting for the front might be better handled with a simple waterproofed power outlet. Cheaper too All that said, I'm not a licensed (or trained) electrician so add several grains of salt. Re: Electrical Planning - Exterior Electrical 3Jun 28, 2013 7:39 pm Thanks Lurgen, We're having three-phase power too so hopefully that will help a but... Lurgen ... My build has a three-phase termination point running to the back of the house on a dedicated circuit ... then your post-handover installer would run it down into the ground, underground to the final location... This is sort-of what we're trying to get away from, the builder will be laying the perimeter paving and so we would prefer the "final termination" of whatever sort to be on the "other side" of the paving. Lurgen .... underground to the final location, and install a waterproof cabinet to house the equipment..... Yes, that's sort of what I was thinking, even if they just terminated the wires somehow and I could arrange the cabinet later..... Lurgen ......LED lighting for the front might be better handled with a simple waterproofed power outlet. Cheaper too .... But I'd still need somewhere to house the drivers ?? Lurgen ......All that said, I'm not a licensed (or trained) electrician so add several grains of salt. I do...and don't What I do, and always advise others to do, is to seek advice (as I am) and consider the responses and if they are simple suggestions then act (or otherwise on them) but if they are "technical" suggestions use them as starting points to ask intelligent questions of specialists in that field !! Quite often the problem is that you don't know where to start and getting advice from forums like this at least gives you a good starting point !! Cheers, P_D .
