What size wire do I need for 30 amps?
For a maximum of 30 amps, you’ll need a wire gauge of 10.
The most common household item that requires a 30 amp circuit is a central air conditioner..
Can 6mm take 40a?
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. Whoever fitted the 40a MCB onto the 6mm cable originally was in the wrong.
How many amps can 1.5 mm cable take?
20 ampsDepending on the installation method used, the 1.5mm cable has a maximum rated capacity of between 14 and 20 amps, so its right on the limit.
Can you mix 1mm and 1.5 mm cable?
So it’s ok even if I have wired half of the circuit in 1.5 and then do the rest in 1mm. Yes, mixed cable sizes are fine provided that the smallest cable is compliant for the size and type of OCPD. AND that the voltage drop for the entire circuit is within acceptable limits.
What is 4 mm cable used for?
The basic application of 4mm twin and earth cable In general, they serve as cables that can be used for the general electrical systems of a given home or property. Thus, it is important that they are applied in an effective and efficient manner to ensure that they are able to supply electricity throughout the building.

How do you determine cable size?
These methods only require minimal equipment and are effective for virtually all cables.Look at the insulation on the cable. Search for text written on the insulation. … Cut the wire with your wire cutters. … Measure the diameter of the cross-section in inches. … Divide the diameter of the wire by .
Can I use 4mm cable for sockets?
2.5 mm^2 is the most popular socket circuit cable. … 4 mm^2 is used for 30/32A radial circuits, and also for 30/32A ring circuits where the cable will be in contact with insulation or a large circuit is needed and voltage drop is a limiting factor.
What size cable do I need for outside sockets?
2.5mm2The choice of cable running to the exterior socket should be, as a minimum, 2.5mm2 twin and earth (TWE) housed in conduit, which could be the mini trunking type or a round design.
How many amps can 2.5 mm cable take?
23-25 ampsA 2.5mm cable is capable of supplying around 23-25 amps depending on the method of installation, so is fine, safe and compliant on a 20amp circuit breaker.
What cable is suitable for outdoor use?
Once outdoors, you should supply your lights via 1.5mm² three core steel-wire-armoured cable (SWA). Make sure that you only fit weatherproof lights that are suitable for outdoor use and that your circuit is RCD-protected.
What size wire is used for lights?
As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.
What size wire for LED can lights?
Typically, a 12-gauge cable with two insulated conductor wires and a ground wire are used. The cable is jacketed with a non-metallic plastic jacket to protect it. The cable is pulled through the pre-drilled holes, starting at one end of the new circuit and working toward the other end.
Can I use 1mm cable for sockets?
Yes, 3 core is required for 2 way lighting circuits. Personally i always use 1.5mm t&e for lighting, but either 1mm or 1.5mm is ok.
Can I use 2.5 mm cable for sockets?
2.5mm Twin and Earth is commonly used as indoor domestic cable. The most common use for this type of cable is for circuits that provide power to sockets. It is made up of two cores and an earth core which must be covered with the identifying green and yellow sleeve when installed.
How many lights can I put on one circuit?
50 watt light equals less than 1/2 amp current flow at 120 volts. You can put up to 30 lights (based on 50 watt light) on a 15 amp breaker. You can put up to 40 lights (based on 50 watt light) on a 20 amp breaker.
What is 1.5 mm cable used for?
1.5 mm is most commonly used for lighting circuitry and switches. 2.5 mm is most commonly used for ring mains, plug and socket wiring. 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.
Is 1mm cable OK for lighting?
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 I use 2.5 mm cable outside?
You’ll need at least 2.5mm wires, radial circuit i.e. only one wire out will suffice if the total load is less than 20A, if above that but less than 32A then a ring circuit (one wire out and another back).
