Hi, Can anyone tell me where or can supply 18 gold coloured deflectors for my spa bath. They are about 3/4 " diamater with what looks like an 1/8 bsp thread to screw into the bottom of the bath. Supplier no longer trading and no marking on the system to tell me who made or installed the system...

Sounds nice, how much do you want for them.

As the T Man said above, a PIR is the industry norm of checking existing electrical installations. If you need an electrical installation certificate then this would have been issued by the person carrying out the works at the time. This was pre Part P and remains so now.

Are you saying that the board has no earth connection.

Thanks for the replies, NHA, will be looking around for the info you suggested. Ricicles chart was small but as you said didn't give the info I thought I required. The 40kA was the pfc at the board as a single phase measurement then doubled as per the rule of thumb in GN3. I appreciatte this is...

NotHimAgain, Yes I am trying to find out if the upstream protection of the BS 88's are going to protect the 3Ka mcb's. The 40Ka PFC was measured at the supply of the dissy board, which is 2 feet away from the fuse box with the BS88's in. The factory has the supply transformer 400 yds away hence...

Hi, Does anyone have the time current graphs for BS88-2 315 amp fuses, got a site with 3Ka mcb with a PFC of greater than 40Ka. Upstream protection is BS 88-2 315A fuses. Would like the graph to see what current fuse would rupture and when, its a 3 phase installation. Tried Google but to no...

Thanks for that,it is slowly making sense. I will await for further advise and try and speak to the Siemens on monday.

Thanks for the reply, so I can remove the econ 7 heater circuits and place in the house circuits board? Is it best to leave the immersion on a seperate board so it only uses the cheap rate or does the new meter not work like that.

Bit of advise required please. Been asked to replace old metal clad econ 7 fuseboard and normal household fuseboard to new consumer units. Customer is changing over to economy 10 which I don't have any experience of. Is it just a replacement for economy 7 or can the board be removed and all put...

I have always issued an EIC to cover the new circuits fitted but was curious as to what others do or is the interpretation of what certificate is required. BC are usually happy with the EIC and have never raised an issue.

Finishing off tomorrow a garage consumer unit with 1 mains radial and 1 lighting radial. It has been fed from a socket as a spur from a FSCU as they had just had new carpets fitted and dont want me ripping up floors to get a supply. My question is, is this an addition to an existing circuit and...

Just started a PIR on an old factory distribution room and it is older than me. Boards are old squared d with bs 3871 breakers. Info from the side is little confusing so would appreciatte pointers on obtaining the short circuit capacity. Marked up as Category of duty M3, instantaneious tripping...

Thanks for the link, I have spoken and now booking. Just what I need. Thanks again

Peeps, Can anyone recommend a heating control course, just been made redundandant and need to up my skills on heating control. Used to do industrial electrical maintenance but now having to take on more domestic so would like to get ahead of the game just in case. Any good manuals etc would...

Is the desk an extraneous conductive part? If not then by bonding it you have introduced an earth potential so making the set up dangerous. I could be wrong in my thinking but that is the way I was taught.

Didn't the Megger MFT have a fault on the no trip setting, how old is your MFT, it may be worth contacting them as they carry out a mod FOC.

Am I missing something? You said 17th edition wiring Regs - City & Guilds 2382 Part P - EAL VRQ Level 2 for domestic ELECTRICAL installers . To be part P registered you have to be a member of a registered body so I do not understand your Part P claim, can you clarify please. Personally I...

There is no reg for depth of burying SWA, it is a judgement call of the person doing the work. If the area is liable to be dug up ie for planting plants etc then the deeper the better. If going across an area that will be left untouched or under a patio then I usually dig to 400mm and place...
