My basic knowledge is fine, if I got my college books out and spent an evening working it all out, I am sure I could nail this scenario down, however its a little outside my recent experience (the specific scenario of exclusively multiple single phase socket outlets on a 3 phase supply) & if I...
Agree that the 100mA intermediate RCD is superfluous as there is indeed an 's' type up front however this rcd is the mainswitch in the board feeding the sub and is of an 'historic' type, so replacing it with a mainswitch of the correct type might be difficult and add to the cost of the job if...

Called out to elderly couple's house today - no power. All 3 lighting circuit breakers are tripped and mainswitch is off. Quick check reveals PIR lightswitch faulty and 1 lamp failed. Replaced the PIR switch for standard 1G2W switch and reset everything, seems fine now. Question is, how did...

Thanks for reply. Yes box is identified and gland is external to box but has a very tight fitting shroud entirely covering gland. Yes, I would have preferred to use 6181Y but can't seem to readily find it in sizes below 10mm and there was no space to fit a bigger box to terminate a larger size...
Hi All, Just thought I would run something past the collective wisdom. Recently did a job that involved the conversion of a garage remote from the house to a small habitation space. The old install was supplied from the house via 6mm swa on a 30a BS3036 with the earthing connected to the house...
Thanks very much for your quick & helpful reply. Haven't had definitive info on floor finishes yet but I think it will be engineered wood in some areas and tile in others. Am going to await the results of the heating engineer's report and will be in touch if we are going to proceed with this...
Hi all, Looking for advice, I am an experienced electrician and have been asked by a customer to install electric underfloor heating throughout a converted victorian chapel as a primary heat source. The customer is open to all options. I am intending to have a professional appraisal from a...
