What size wire is needed for a 30 amp circuit?
Any circuit fused for 30 amps must use a minimum of 10 ga copper or 8 ga alu.
Longer runs may require an upgrade of wire size..
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.
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.
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).
What size cable do I need for 32 amps?
For 32 amps you would require 6mm twin and earth cable.
Is 2.5 mm wire enough for 1.5 ton AC?
Your 1.5 ton ac draws around 8~9A and should run on 2.5 mm wires even though 4 mm is better. Finally, length of the wire also plays a crucial role when choosing wire gauge. For installations longer than 30 metres use the next bigger size wire. Lengths are measured from meter/main juntion box.
What size wire do I need for AC?
It’s going to completely depend on the unit that’s being installed, but commonly it’ll be 30-60 amp with 10-4 AWG wire. You’re probably looking at a 3.5 ton unit, so you’ll be in the 30-40A (10-8 AWG) range. It might be worth it to get a few quotes from local HVAC companies, and see what they want to install.

What is 1 mm cable used for?
1mm cable can be used for fixed wiring loads besides lighting crcuits if the maximum load is within the guidelines for the current capacity and installation methods. Some light duty flexible cords are made from 1mm flexible cables.
How many amps can 1.5 mm cable take?
20 amps2 Answers from MyBuilder Electricians Depending 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.

What is the current rating of 2.5 mm twin and earth?
20 to 23 ampsRatings for Twin and Earth Electrical Cables For example, the current-carrying capacity of 2.5mm twin and earth cable is 20 to 23 amps.
Is 1mm cable OK for lighting?
1mm unless exceptionly long runs or other unusuall circumstances need larger. 1mm will be run at less than half its rating in most circumstances, if we consider 1.5 to be needed for lighting, then by the same logic for a 32 amp radial we should select cable suitable for about 60 amps !
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.
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.
What is 2.5 mm cable used for?
2.5mm is commonly used for behind sockets, while 1-1.5mm is most often used for lights (depending on how many lights you have in a circuit).
Is 2.5 mm AC cable safe?
If the electrical system is properly designed, circuits are generally protected by circuit breakers or fuses at their source. … If the standards are similar in your location, your 2.5mm wire is fine for a 15A circuit. Your air conditioner draws 1550 watts at its rated 220 volts, which translates to about 7 amps.
