I am about to design an installation for a client..I have done the donkey part of it, but thought that it might be an idea to post here to see how you guys get on with it.
Installation spec.
Install 108 No lights along two driveways, 40 on the main driveway and 68 on the secondary driveway.
The main driveway is 240 meters long and the secondary driveway is 428 meters long.
Each of the lights will be 500mm high bollards containing one 18w TL-D lamp.
Main Driveway:
These lights are to be operated via a photo-cell and a timeclock to prevent them being on all night, however there will be a requirement for a remote over-ride switch for when there are functions. All these lights will be on one side of the driveway and must be on one circuit.
Edit:
Total circuit length is estimated to be 286 meters
Secondary Driveway:
These are to be operated by a phot-cell, however the supply to this will be via two way switching at either end of the driveway, the switching being controlled by motion sensors which link to a timer that automatically shuts the lights off after 20 minutes.
Edit:
Total circuit length is 472 meters
Now you need to work out how to achieve this, and calculate the correct cable size to comply with the regulations.
I have done all the above already, I am simply adding the finishing touches and pricing it up..I am doing a quote, but we have been given the go ahead regardless, the quote if for cost control purposes and client reference.
