You seem to have the responses you were looking for so i hope you don't mind my question! is it really acceptable to apply diversity and assume the whole cuurrent isn't demanded? I no its allowable but do most electricians apply it?

Its a coaxial flue, but there are 2, 45degree bends in the boxing, will this cause any problems?

hello and thanks to all that answer, I have a RGI coming to do a landlords inspection on a combi boiler and just wanted to ask if the entire flue has to be exposed? although it is accessible it requires the removal of boxing witch is filled,corked and painted. should i remove it prior to his...

got it, cheers!

thanks for the the explanation, i now understand the 30mA but how does this relate to how many circuits you can have connected to it? this reply may be confussing me? will read up more on the bathroom bonding. cheers

Okay but if the extraneous pipe work is sufficiently (tested via measurement) bonded to the MET ,via pipework and boiler bonding, no further bonding is required - is that correct? If so is this testing beyond the scope of i DIYer? How do you no how much can go on a RCD? obviously the...

how is the 30mA calculated? it currently has the upstairs lights/fan (6A MCB)and shower (32A MCB) I'm not sure until i check next time i'm there but i think it has the kitchen sockets on it aswell. are all RCD's 30mA? such as copper pipes? all my pipes are boxed in or in a vanity unit...

like no-nonsense!!! :D cheers

hello and thanks to all that reply, I'm afraid its another bonding question!!!! currently: The water and gas are bonded direct to the MET (within 600mm) All the pipes at the combi boiler are bonded together, but not to the MET or any other circuit The boiler is about 1 metre from...

I would prefer to get an RGI to do both as you've suggested, would the RGI have to certify it as his own work (providing there are no problems) and thus making it very hard to find somebody willing to do it? or can he certify it on the fact that my work has been suitably checked?

To sum it up then, obviously it should of been done by a RGI in the first place. however it wasn't so i should inform building control more than likely involving an inspection and then get a landlords certificate. is that correct?

i'n not implying i'm 'qualified' to do the work, i've made it clear i know i should of had it connected by a corgi, i was just trying to inform you that i'm not a complete biff like some of the threads on this site so i get the answers on how to correctly get it checked ready to rent the...

Hello and thanks to all that reply, I’m sure this post will cause a reaction will all corgi guys but I am going to post it and see what responses I get. I have moved an inconveniently positioned combi boiler to a new position in a small house including connection and a new flue system (6...

just found this, helps but nothing about zones.

hello and thanks to all that answer, Just wondered if anyone can explain the IP ratings for lights, I know it relates to the safety requirments in a bathroom, but does each IP rating relate directly to a specific Zone. if so which relates to...

thanks for the info.Tidies the way forward! second only to safe!

after looking at your diagram again, i'm guessing the "in enclosure" bit implies it would be fitted in the loft or similar and enclosed in something similar to this......... is this correct?

Not seen one of them before, it looks like it belongs in a CU,is that correct? or can it be fitted somewhere near the shower/fan i.e in the loft

This seems to be exactly what i wanted to do, am i right in thinking the contactor in enclosure is a relay? any ideas where such a device for this application can be purchased?

i'm away from the house for a while so no pics for now! had assumed one upvc windows lock was similar to that of another!! but as you have so colourfully illustrated:-
