Hi there,

I am putting in an outdoor spot light (500w) that will be mounted on a pole approximately 20m from the house and have a couple questions.

The light will have a motion sensor as a trigger and I will be getting a sparky to make the connections to make sure that it is all legal and complies with standards etc.

1) What sort of cable I should be using to run the power? The light will be mounted on a power pole and I would like the ability to add more lights (with sensors) in the future if needed. I intend to also mount a security camera in the same area too. I am assuming that the cable will need to go into a conduit of some sort for water proofing, under the ground and up the pole.

2) I have an existing outdoor light with a sensor under the eaves. This light is on the lighting circuit and I have a control inside the house that I can set to auto, off or on. It would great if I could hook into this, purely for the control of the 500w spot light (I dont need the existing outdoor light under the eaves).

3) With the security camera, I understand the cable will depend on the type of camera that is put in. IP or  CCTV. I am most likely to put in an IP camera so am thinking about using CAT 5E cable. Is there any limitation on outdoor use and also length of the cable? I plan to run the connection into my router. Fairly sure I have to run this in a different conduit to the power, due to interference.

Any help would be apprecaited.

You electrician should sort the power cable, you shouldn't have to supply this to him. Discuss the switching and future requirements with the electrician and you should hopefully be able to tap into your existing switch etc. Just beer in mind that the cable is probably now going to run in a different direction, so there may be more work than you initially anticipate.

Yes, you don't want to mix mains and low voltage cable in the same conduit. If you discuss the job with your electrician you may be able to do parts of it, like dig the ditch etc to save some money.

You can get underground/direct burial rated cat cable, though some are very happy to just run normal stuff inside it's own conduit.
