For a mains 220v – 240v provide you must use top quality Metal Wire Armoured (SWA) cable. WA ( metal wired armour) cable. FIG 1 beneath reveals.

1.5mm² copper conductor dimension, Nominal Total Diameter 11.54mm 3 Core Cable with Brown, Black & Gray colored cores as indicators Prime quality Class 2 plain annealed stranded copper cores to BSEN 60228:2005 (Beforehand BS6360) Insulated with XLPE (Cross linked polyethylene), Bedded with PVC (Polyvinyl Chloride), Armoured with SWA (Metal Wire Armoured) and Sheathed with Black PVC (Polyvinyl Chloride) Appropriate for voltages as much as a most voltage of 600/1000V Most present of 23A Appropriate for Temperatures between -15°C and 90°C Conforms to BS5467, IEC 60502, BSEN (IEC) 60332-1-2 and BSEN 60332 Metal Wire Armoured Cable, generally often called SWA Cable, is a tough sporting energy cable which is designed for the provision of mains electrical energy. Appropriate to be used in energy networks, underground, inner, exterior purposes and to be used in cable ducting. It may also be related to an earth through a Cable Gland which can give the cable additional safety. The metal wire armour sits beneath the cable sheath to supply safety to the conductor and insulating layers which suggests the cable can stand up to excessive stress and be buried immediately underground. Cable provided as 50 meter Reels.

FIG 1 SWA Cable

Mains 220 – 240v Rubber butyl cabling

Many mains 220 -240v fittings will come provided with a size of three core cable to allow your electrician to attach the cable to the SWA cable supplying your mains electrical energy to your gentle fittings. Nonetheless, not all fittings will come provided with mains cabling and subsequently we suggest you employ HO7RN-F 3-core rubber cable (rubber butyl). That is the very best kind of mains cabling you should use when putting in your mains gentle fittings to your mains SWA electrical energy provide. It’s going to tolerate excessive and low temperatures and is extraordinarily arduous Waring. DO NOT USE PVC cable to hook up with your SWA provide as PVC breaks down over time particularly with publicity to UV ray and is answerable for the various poor installations we hear about because of capillary motion the place moisture will get into the connections and results in the fittings breaking down and quick circuits blowing the LED chips and sometimes tripping the RCD unit. Mains cabling is extra temperamental than 12v because of 220v – 240v going on to your fittings, subsequently is much less tolerant of any water ingress points. So for peace of thoughts persist with rubber not PVC and guarantee all connections are completely watertight. The cable needs to be buried to a protected depth to keep away from any pointless threat because of backyard forks or spades. The thickness of the cable helps with the voltage distribution over distances. FIG 2 beneath reveals an instance of three core HO7RN-F rubber cable.

12v rubber double insulated cable

If a 12v low voltage system is being put in then versatile rubber spherical double insulated cable needs to be used. DO NOT USE PVC cable. Once more utilizing HO7RN-F however as 2-core rubber cable could be the very best low voltage cable we might suggest on your 12v set up. The thickness of the cable helps with the voltage distribution over distances and in contrast to 220v – 240v the low voltage 12v cabling is healthier utilizing thickness of 1.75mm² or extra for lengthy runs over 15 metres. We are able to provide 12v cabling too. FIG 3 beneath reveals an instance of two core HO7RN-F rubber cable.

Cable Ducting Electrical (PE) pipe

We get requested quite a bit about tips on how to shield 12v 2 core cable within the floor. In contrast to SWA cable 12v 2 core cable will not be metal wire armoured and subsequently rodents can chew into 2 core cable within the floor. A simple answer could be to guard the two core cabling inside Electrical cable ducting conduit tubing. This can be a low cost and easy method to shield the cabling and towards being by accident lower with backyard gear or backyard forks. FIG 5 beneath reveals an instance of conduit pipe and FIG 4 of Electrical cable ducting pipe you may get hold of on-line for a lot of constructing and {hardware} suppliers. Electrical Cable Ducting is on the market in 32mm bore, 38mm bore and 48mm bore, in each 50m and 100m coils. PLEASE MAKE SURE YOU MARK THE CABLING SO EVERYONE KNOWS YOU HAVE ELECTRICAL CABLE INSIDE. Don’t use water pipe because it might be assumed that water or gasoline pipes are inside and will then trigger electrical shocks if lower by.

RCBO Shopper unit

The place alarms and CCTV installations are involved it’s extra environment friendly to have a devoted RCBO defending every particular person circuit, particularly the place mains voltage exterior lighting is worried. The instance beneath is a 32 amp 30mA RCBO Single module 30mA sensitivity mixed MCB/RCD. New compact dimension RCBO permitting for max utilization of cable area throughout the Shopper Unit and straightforward set up. FIG 6 beneath reveals an instance of an RCBO.

Cable Joints

Equally as essential and doubtless the weakest hyperlink in any exterior cable run is the becoming a member of of cables. Every joint will must be 100% water tight and this may be achieved by way of Magic Gel poured into exterior weather-tight junction bins as soon as the termination is full or you may use warmth shrink kits. See FIG 7 and FIG 8 beneath. Burial resin mixes are additionally obtainable to make use of in weatherproof junction bins and this product units to a really arduous resin and never splendid if you should get to a joint afterward, however splendid as a everlasting water tight repair. The place attainable try to maintain all low voltage transformers and joint bins above floor, this can cut back the danger of water ingress. Poor installations ignoring the significance of sealed cable joints can result in Capillary motion which is a means of moisture (Liquid) flowing or being drawn again by the cabling into the fittings.
