Can I use 4mm cable for lighting?
The amount of current that the cable can take will be limited by whatever the fuse/MCB is for the 4mm cable at the supply (house?) end.
For 4mm you will probably be looking at a mximum of 32amps.
The 63A you refer to is the MAXIMUM amount of current that the device at the SHED end of the 4mm cable..
How many kW can 32 amps take?
15 kW”A 30 or 32A circuit is usually appropriate for household or similar cookers of rating up to 15 kW. A 50A circuit would, as I said, give a higher margin of diversity.
Can 4mm take 32 amps?
Yes, provided the run is not too long, check volt drop, 4mm is ok on 32 A CB but not on BS 3036 rewireable. Use a 16A commando style plug and socket or hard wire it. “is it ok for a 4mm to go on a 32 amp??” You could probably put the machine on 2.5mm 16amp ctype mcb using a commando plug & socket.
What size cable do I need for a 32 amp supply?
32 & 40 AMP electrical requirements For a 32AMP hot tub, 6mm² 3-core SWA cable is needed and a 10mm² 3-core SWA cable is perfectly suitable for a 40AMP Hot Tub. An IP65 45AMP Rotary Isolator Switch is also recommended so that the hot tub can be isolated outdoors in an emergency or for service work.
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.
Can I use 4mm cable for cooker?
Cookers don’t always pull their max possible current due to diversity, but should really be wired in at least 6mm. I once came across a 8.5 Kw shower wired in 4mm, and the cable got quite warm when in use.
How much load can a 4mm copper wire handle?
Depending on the atmosphere and how you place it, the carrying capacity of 4mm sq copper wire is 20–25 Amp.
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.
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.
Is 2.5 mm cable OK for cooker?
A 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.
Is 6mm cable OK for 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.

Is 6mm cable OK for 9kw shower?
Showers up to 9kw may carry a 6mm cable as long as the shower unit is within 18 meters of the fuseboard. Fuses and switches should be rated at 40 amps. Showers up to 12.5kw should carry a 10mm cable to units within 35 metres of the fuseboard. Fuses and switches should be rated at 50 amps.
Can I use 6mm cable for a 8.5 kW shower?
6mm cable, depending on the run, is likely to be fine for an 8.5kW shower. Rcd protection is helpful, but bonding and cross bonding are far more important. And a 30a breaker, fuse wire wouldn’t pop for overload either as it’s unlikely to be overloading long enough.

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.
