So I have a job of installing an old cast iron lampost which will need to be buried into the ground about 600mm deep due to its weight. I am planning on drilling a hole at an angle from the patio area (next to the hole) into the hole to pass the 1.5mm swa into. Once the cable is in, I’m planning on concreting over the cable so that the cable is in the middle of the concrete foundation and the lampost will sit over the foundation and so that the cable doesn’t get damaged when putting the lampost in the hole. Question is, do I need to put the 1.5mm swa through some duct/copex before concreting or can I concrete over it bare? There is no chance of replacing the cable in the future if needed anyway unless the lampost gets dug out again.
Also I am going to terminate the swa gland into a plastic enclosure which will house a quinetic receiver (supply side). When using the piranha earthing nut, what size cable should I use for the fly lead from the piranha nut to the connector block with the other CPC’s? Could someone also tell me where they got the cable size of the earth fly lead from please. I feel like if I use a 1.5mm I am downgrading the resistance of the armouring...
If I was using a bigger armoured how would I know what size earth fly lead to use. Also for metal containment... would like to know for future use.
Thanks for any help I receive
