Hi All, first post.
I'm a 16th edition sparky considering a return to the trades and wonder if anyone can advise on the major changes 17th ed has introduced.
After reading a few bits and bobs, it seems any new sockets installed to new/existing circuits need rcd protection, or any other circuit for that matter considering the 30mm rule? Out of interest how does everyone think the customer will respond to the increased invoices?
I've also noticed that insulation resistance has increased, is this for all domestic installations?
One last area that has always bugged me regarding bathroom bonding. Do you need to bond a radiator if it is piped in plastic.
Example, an existing radiator is piped in copper and then replaced for a towel rail using plastic pipe under the floor boards and then chrome up-pipes to the towel rail. Does this need bonding? As far as I knew, only extraneous metal work that introduces a potential difference needed bonding, ie, the pipes not the radiator!?
Any help appreciated
Cheers,
tomlini
