Electrical cable advice

[shaneo]

Thanks to everyone for the advice, will be running a 25 sqmm up to the house and then a surfix back down to the gate as lighting will be required at the gate, and because of gate location, theft or damage to a kiosk or DB is a possibility. Does a 4 sqmm sufix supplied from a 5A circuit breaker sound right? And can I run them in the same trench?

It sounds ok ...however i would still check the tables and make sure...running the 2 in the same trench shouldnt be a problem so long as you dig the trench deep enough for the surfix unless you use mechanical protection...a 25 mm ecc cable already has mechanical protection.

just a note with regards to theft ...mounting cameras visible to the criminals and mountin them high up on the side of a building is not smartest thing to do...if you have a crime issue...use facial recognition cameras which are hidden low enough that they can see the face and not cover by a hood or cap...the new systems will alert you if a person is trying to hide their face and send you a notification...cctv is becoming a more reliable form of crime detection...back in the day when 480 line cameras where used ...they were more for movement than anything else...new technology has made them a much better crime prevention tool if installed and setup correctly in the right locations.

something else while of the crime subject...cctv ...wireless nano units etc etc ...for neighborhood watch is becoming a very useful tool...if you are smart you will have a fibre cable installed to a point get the max speed available and not suckered by companies trying to screw you with FUP clauses...then fit cameras around the hood...with wireless nano stations which will serve 2 purposes.

one give all the patrollers access to free wifi making it easy to link to cameras setup around the hood to view if required which would mean you can stream in HD...and saving you tons of cash having to pay to transmit via cellphone networks...you dont need to send the data to a XVR and them try download later blah blah...something to think about...just make sure the network is secure.
