32 Amp Hot Tub Cable Size

Wire size chart and maximum amp ratings.

32 amp hot tub cable size.

The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. What cable should i use for a hot tub is a question we often get asked and when it comes to wiring your hot tub you have lots of cable options available to you depending on the environment and protection you might require. We have listed many of the cables that customers and electricians have requested from us over the years to try and make it easier for you. Also a light inside and two outside down lights and 32amp supply for a hot tub.

The reactance for single core cables is selected from the flat touching column in from table 30 in as nzs 3008. Not suitable for ring mains. 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. Cable length in mtrs.

For a 32amp hot tub 6mm 3 core swa cable is needed and a 10mm 3 core swa cable is perfectly suitable for a 40amp hot tub. The institute of engineering and technology iet formerly the institute of electrical engineers iee have decreed that cables can carry loads measured in amps according to not just their size but according to the methods they are fixed or otherwise to any given surface. Loading a cable with too many amps makes it hot and hot cables are dangerous. One electrician has said to use 16mm armoured cable and the other has said 6mm armoured cable.

Enter your proposed cable size type of insulation voltage ambient temp 30 is norm your cable length and circuit load in amps. The reactance for multi core core cables is selected from the circular conductors column in from table 30 in as nzs 3008. The cable sizing calculator uses the resistance r c from table 35 in as nzs 3008 at 75 c. This is the worse case scenario.

This is the worse case scenario.
