As for the fuse well a 60amp fuse will continue quite merrily for over an hour at 2 times it's rating (120amps) so you may find that it is quite adequate i would though contact the dno/bg and ask tell them that the guy wanted to fit an 80amp fues for you, upgraded your tails to suit, but was unable to fit one and only fitted a 60amp for temporary. Main fuse rating. The main circuit breaker is really no different than any other breaker, but it is designed to handle the large amperage load of the main feeder wires bringing electrical power to the house for this reason, it will be by far the largest breaker in the box in terms of amperage rating.
main fuse rating
Lucas fuses have three ratings; the continuous current they are designed to carry, the instantaneous current at which they will fuse, and the continuous current at which they will also fuse the figure found on lucas fuses is the continuous fusing current which is twice the continuous ampere rating that the system should be using; this can be a. I have a bit of hurdle; i couldn’t find the fuse rating on the main fuse box. should i ring the dno for this info? you see, i really don’t want to break the seal (law) to look inside. thanks.. A main fuse can blow, leaving the branch-circuit fuses intact, with nothing else apparently wrong. this can happen wherever the combined rating of the branch-fuses exceeds that of the main fuse. for example, if the main fuse is rated at 100a, with 10 feeders fused at 20a each, they could all be loaded to 10a to 15a..
