[QUOTE="Doc Hudson, post: 484794, member: 1607"] Unless the circuit is just a single radial cable with no branches off it AND no other parallel resistances, (other lights / extractor fans etc. still in circuit), AND you are 100% sure that the fault is a dead short across conductors, then any resistance values you may have read/calculated are a bit hit and miss. Most lighting circuits end up with numerous branches going off to switches or lights from the main supply cable. Resistance per meter for the common CSA copper conductors are in the Appendix of the On-Site-Guide. Are you sure your symptoms do actually relate to a short of some sort? Doc H [/QUOTE]
