Question: What Size Armoured Cable Do I Need For Outside Lights?

Is 1mm cable OK for lighting?

A lighting circuit is protected by a 5- or 6-amp fuse or circuit breaker.

Lighting circuits are generally run in 1mm2 two-core-and-earth cable, but particularly long circuits can use 1.5mm2 cable to compensate for the drop in voltage experienced on long cable runs..

Can 6mm take 40a?

2 Answers from MyBuilder Electricians 6mm twin and earth cable (which this almost certainly is) can be backed up by a maximum of a 32a MCB, even lower if other factors are involved. You’ll need that 10mm cable and a 40a MCB unfortunately as your shower is going to draw over 32a.

Can I use 2.5 mm cable for lighting?

You can use 2.5 mm² cable of course. … In large buildings sometimes 4 or 6 mm² cable is used on the feeder runs, and near the light fittings the cables are branched off in J-boxes to 1.5 mm² to go to the light fittings, to compensate for voltage drop. These light circuits are often controlled through contactors.

Can you run Armoured cable above ground?

No problem running the cable above ground, so long as the cable is suitable for the weather and for any likely mechanical damage it may suffer. I would choose 3 first, or a modification of 1 to have armoured cable run on a specific support structure near ground level.

Is 6mm cable OK for a cooker?

The cable should be selected to cater for the Maximum load of the circuit, the MCB is selected to protect the cable. You should NEVER do it the other way round. … Plain and simple you need a 10mm cable, 6mm is not correct, it may work but may also burn your house down, you take the risk.

What size wire do I need for 30 amps?

“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

Can I use 6mm cable for a 9.5 kw shower?

9.5kW is either 39A or 41A depending on the voltage it is rated at. 6mm cable is 47A when installed in the most favourable conditions. So 6mm could be used, depending on how it is installed. However it would be usual to use 10mm which would allow the fitting of a higher rated shower either now or in the future.

What size of Armoured cable do I need?

A 16mm cable will be ample for the required load and also satisfy Volt drop requirements. Literally, using 16mm will be energy saving as Energy lost through Volts dropped across the length of the cable run will be at a minimum.

Does external cable need to be Armoured?

Armoured for underground, generally. Mains outside would be preferable if in waterproofed conduit, protection should be RCD type too. … Or you could run it along the back of the wall in earthed steel conduit or heavy gauge pvc conduit. Butyl flex is rated for outdoor use but has no mechanical protection.

Does Armoured cable need to be in conduit?

Whilst the weight and rigidity of armoured cables can make them hard to handle and time-consuming to terminate, they are essential in applications where unarmoured cables may be prone to damage and require containment protection, i.e.: conduit or trunking.

Can I use 1.5 mm cable for sockets?

The cross sectional area of the earth wire in a 1.5mm cable is 1mm and in a 2.5mm cable it is 1.5mm. This should be sufficient for most domestic socket and lighting circuits.

What is 4 mm cable used for?

4 mm is most commonly used for high power ring mains, plug and socket wiring. 6, 10 and 16 mm are most commonly used for high powered small appliances such as cookers. This cable is suitable for indoor use only.

What is 6mm cable used for?

6mm cable is normally used to power a cooker and or a hob. In older propertys you may find it has been run in to supplie a shower however 10mm is more appropriate now.

Exposed or buried wiring must be listed for its application. (Type UF cable is the most commonly used nonmetallic cable for residential outdoor wiring runs.) UF cable can be direct buried (without conduit) with a minimum of 24 inches of cover.

Is Armoured cable waterproof?

As others have said armoured cable, we have lots of it running fom the house down the garden to get power to a shed, greenhouse, workshop and exterior power point. It has the normal plastic coating and thus is waterproof.
