How thick should the earthing wire be?
1.5 mm is fine. You don’t need to use both of the earth terminals in a normal domestic environment though, it’s only used in situations where ‘high integrity’ earthing is needed, usually where there are lots of computers on the circuit.
What is 16mm earth cable used for?
The table below shows the current carrying capacity of 16mm twin and earth cable. This cable is mainly used for large electric domestic or commercial cooker and shower circuits rated at 50A AMP.
How do I choose earthing cable size?
Earthing conductor size calculation Formula:
- Earth conductor size PE(Sqmm) =1.5 x √ (I(Fault-A)2 x t(s)) / k.
- Earth Conductor size = √ (200002 x 0.5) / 80.
- However, the size of the conductor is above the resultant size.

What kW can a 10mm cable take?
10mm cable should be used on showers of 8.5kw and above, so yes if your fitters are saying that the best showers are those with the highest rating (e.g.10.8Kw), then they are right in that the 6mm cable is inadequate.
How many amps can 10mm cable take?
Can I run a 10kw shower on 6mm cable?
Fuses and switches should be rated at 32 amps. 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.
What is a 10mm cable rated at?
How many amps can 10 mm cable carry?
Why is earthing wire thin?
If the current is smaller then the resistance can be increased by using thinner wires without too much of a loss of energy.
What size cable is used for earth bonding?
Bonds should be at least half the size required for the earthing conductor, min 6mm2. So provided your earthing conductor need not be > 12mm2 I don’t see a problem. You’d probably have to use the adiabatic equation to prove that <16mm2 is OK, but chances are it would be.
How is earthing size calculated?
Required Earthing Conductor size = Cross sectional area x Total allowance x Safety factor. Required Earthing Conductor size = 1125 Sq.mm say 1200 Sq.mm. Hence, Considered 1Nox12x100 mm GI Strip or 2Nox6 x 100 mm GI Strips.
