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 !.
How do you calculate cable size?
Current rating for 35°C (95°F) = 31 x 0.97 = 30 Amp. Since the calculated value (30 Amp) at 35°C (95°F) is less than that of current carrying capacity of (7/1.04) cable which is 31A, therefore this size of cable (7/1.04) is also suitable with respect to temperature.
What is the current rating of 6mm cable?

What size wire is rated for 100 amps?
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.

What size wire is rated for 60 amps?
4-gauge wireIt’s recommended to use a 4-gauge wire for 60-amp appliances like an electric furnace or a large electric heater. While it’s common to use a 6-gauge wire for 60-amp breakers in practice, it’s best to use a 4-gauge wire if you’re installing a 60-amp subpanel.
What size cable do I need for 32 amps?

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 size wire do I need for 30 amps?
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. In your case, use at least 10 copper for your welder regardless how far it is from the breaker panel.
What is 2.5 mm cable used for?
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.
What size wire do I need for a 200 amp service?
For a 200 amp service, you will need to use a #4 AWG wire for copper conductors, or a #2 AWG for Aluminum or Copper-Clad Aluminum.
How many amps can 6mm cable take?
Subsequently, question is, how many amps can a 4mm cable carry? 4mm clipped direct has a current rating of 37 amps, all other installation methods drop that rating down below 32 amps….How many amps 6mm cable can carry?Cable sizeRating in Amps1.5mm202.5mm274mm376mm47Mar 26, 2021
Can 6mm take 40A?
40A is too high for 6mm, should be 32A. Also the length of the cable run has a big impact on whether 6mm is a big enough cable…..! Its generally ok but can struggle for long runs.
What size wire is rated for 400 amps?
1,000 kcmil400 amp service requires a wire size of 1,000 kcmil.
Is 6mm cable OK 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 is 4 mm cable used for?
If wiring as spur the 4mm is required to allow a 32amp feed. But on a ring main with 2.5mm you can fit a third cable and take a spur but 4mm is normally too thick to allow a third cable to be fitted. If one needed a longer run then 4mm ring could allow this.
