I want my fuse panel upgraded and wondering what would be a reasonable price, I currently have one RCD that coveres the power circuit only, I had this fitted late 1980s. I want the single RCD removed and replaced with individual RCCB units currently all are just cartridge 2x16a 2x10a stove hotwater plus a two way inlet swicth and an inlet socket fitted for a generator curious what cost of labor on something like this would be for a sparkie to do this job. also is it still legal to put the stove and hot water on just a CB or do they require RCCB now. |

If its just a case of fitting a few RCCB's, then its probably an hours labour, plus travel and parts. That assumes there are no surprises. There are usually surprises. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

thanks Glen, the old fuses would need to be removed and a housing for the new RCCB's and assume a surprise and it takes 2 hours + travel what would $$ estimate be as I have no idea on what the hourly rate would be. and are CB still OK on stove and hot water? |

You wouldn't fit RCCB's to a stove or hot water as they have MIMS (Mineral Insulated Metal Screen) elements, and there's always enough leakage to trip the RCD. Never seen a stove and hot water fed from the same breaker (fuse) due to quite a large variation in load if both are on at full steam verses just one element on the stove. That would be plain bad practice if it was indeed legal. Do you know if you have TPS (plastic) mains wiring? Or is it....gulp....fabric or rubber coated? Cheers Pete'. |

OK my bad for not making it clearer currently all are just cartridge 2x16a 2x10a 1x32a stove 1x32a hotwater They make RCCB with a higher ma trip current for this very purpose I just not sure if its required for residential use. possibly a good investment regardless |

Ah. That makes more sense  . No need for RCD protection on mims element devices (hot water & stove) Common practice is to run no more than four socket outlets (power points) through one RCD or RCCB. It seems you have two power and two lighting circuits. RCD protection is now required (In New Zealand anyway) on new installations, and installations that are changed for lighting circuits as well. Best bet is to get a couple of quotes from two different sparkies which would point you in the general cost direction. Depending on how many power points you have, there might be extra wiring to split the circuits into no more than groups of 4.Cheers Pete'. |
