How many amps can 6.0 mm cable take?
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.
How much load can a 4mm cable take?
The standard load capacity of 4mm insulated aluminum wire is about 33A (at 30 degrees C), and 4 mm copper insulated wire is 42A. The bright wire can carry 7000W of electrical power, and the dark wire can generally bear the maximum electrical power at about 5500W.

What current can a 1.5 mm cable carry?
between 14 and 20 amps
2 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.
Can 4mm cable carry 32 amps?
4mm clipped direct has a current rating of 37 Amps, all other installation methods drop that rating down to 32 Amps.
What is the carrying capacity of a wire?
Current carrying capacity is defined as the amperage a conductor can carry before melting either the conductor or the insulation. Heat, caused by an electrical current flowing through the conductor, will determine the amount of current a wire will handle.
What size wire do I need to run lights on circuit?
In most cases 1mm should be fine but depends on how many lights are on the circuit and how long the cable run is. If quite a few are required or the cable run is over a long distance, then 1.5mm cable should be used to cope with supply demand and voltage drop.
