FAQs

How much current can 6mm twin and earth cable carry? ›

For example, if the 6mm twin and earth cable is enclosed in an insulated wall, it can carry up to 32A but if there is a thermal insulation touching the wall then it will be around 23A. One of the highest amp rating will come with a clipped situation – 47A.

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.

The maximum load for a 6mm cable depends on several factors, such as the type of cable, the environment it will be used in, and the application. However, in general, a 6mm cable is typically rated for a maximum load of around 50 to 60 amps for electrical power transmission purposes.

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. Whoever fitted the 40a MCB onto the 6mm cable originally was in the wrong.

Typically used for supplying internal power to appliances such as electric showers, cooker and induction hobs, 6mm twin and eath cable is flat for easier installation into plaster. A range of lengths are available to suit any project requirements.

Is 6mm cable OK for 8.5 KW shower? ›

Yes Carl, definitely 6mm cable will be fine. In fact it often will do an 8.5 kw shower entire supply. I actually would recommend any 8.5 or for that matter, 9 and 9.5kw showers to have the cable from the pull cord to be 6mm so to be easier to install.

Cable size: 6mm. Radial thickness of insulation: 0.8mm. Radial thickness of sheath: 1.1mm.

Yes you can. BUT, I would be inclined to put a FCU on the end of the 6mm cable then run a 2.5 mm cable to where ever you want.

The size 6mm refers to the cross-sectional diameter of the cores so the overall diameter is 18.2mm.

Often electrical showers are rated between 8 & 9KW and take a total of 40 shower amps when they are on. If there are two electric showers on at the same time the total load will be 80 showers amps which exceed the rating of the mains house fuse which could cause it to blow.

The 6mm twin cable is the most common cable run in vehicles to run fridges, etc. The cable is rated at 40 Amps over a 5mt distance and will reduce to approx 35 Amps over 10mt length.

6mm twin and earth contains brown and blue conductor cores with a bare earth which are protected by a durable PVC sheath. Typically used for supplying internal power to appliances such as electric showers, cooker and induction hobs, 6mm twin and eath cable is flat for easier installation into plaster.

40 AMP Wire Size

For a maximum of 40 amps, you'll need a wire gauge of 8. Many electric cooking appliances require 40 amps such as electric cooktops.
