Indeed. A failed diode was not uncommon in early Sony stuff. Quite dramatic too. The real point of mentioning it is to give an easily understandable example of the hard ware. Hoping to build up readers confidence and encourage personal learning. Kind of opposite to many of the superior toned posts

Spikey! All prices are inflated to people of our age, be it a car wash or a boiler install. I don't work for £1.50, I bearly work at all. Bit I guess this is more about you and how you justify your charges (to yourself)

These are common on dell laptops (pre usb c). Recent dell units are 130w. Older ones are 180 and 200w. It is a switch mode supply (smps) so expect over 350v on that 450v cap (nasty. Ask any one who worked on valve amplifiers) The guys on here often suffer 'compassion fatique' and if you can...

Thanks. I'm reading on a phone. A cheap Samsung. It's very hard for me tell the difference between the normal text and the hyperlink. Back in the good old days, hyperlinks were bold and underlined (back then my sight didn't need that help). I may be asking after the wrong thing, your Google...

Hi Richard, I'm not seeing anything in your post. Hope I'm not falling into a trap here..... Thanks

I could have saved some time this week if I had some blanks for tails I pulled from Henley blocks. The hard mushroom type or rubber bungs (add glue) would do. I know Henleys are cheap but these were awkward gits to replace - a blank would have saved me sweltering under the stairs. Anyone have s...

Quite right for cable standards but be careful about sockets vs plugs. You're probably talking about cheap common sockets that require punch down tools. Many 'nicer' sockets incorporate their own 'tool' which is also the socket back. Some of these are much worse than plugs to install. In the...

For the hard of understanding (me). I see the meter cables coming from (guess) supply head not in picture. I see cables from rcd to isolator switch. What offers over current protection to the t&e from the isolator? Company fuse? I know I must be misunderstanding something, as you guys...

Be aware of the twisted pairs in the cable. Your tester will confirm you have connected the pins correctly (1 to1..... 8 to 8) but it won't confirm you have the twisted pairs correctly distributed. Please check diagrams, from memory, it Goes something like; 1 and 2 are a pair 3 and 6 4 and 5 7...

Change motor. Do you also need to change pump or can you select a different pulley to suit the low power motor? It will seem painfully slow though.

Hi Doc, The 'design' is a single 3A fused spur at the end of the cable I've pulled. The spark will be connecting the T&E to the input of the fused spur and the transformers (via the remote switch) to out put of the fused spur. The spark will perform the insulation test then the earth...

12v tanning salon perhaps? Many thanks

Many thanks Deke, I have a little knowledge (enough to be dangerous) but absolutely no electricians qualifications. Over my time (I think) I’ve seen bathroom regs vary to include bonding to all pipes and even a period when an additional link from the pipe bonding to an existing bathroom earth...

Calm down Sharps! The main board is fed with a 16mm earth. To avoid any question of the bathroom earth being too small - if I cant get advice in advance, I will blow £65 on earth cable of that size. 16mm tails feeding a bunch of 12v transformers? that would allow me > 1200A @12v. Bit of an...

Hi Sharpie, The wetroom has its own door. The only electrics in the bathroom are 12v. There are no mains cables anywhere in the bathrroom but I would like to pass one inside the partition wall (but I can avoid doing this if required). I will need an electrician to connect, test, verify...

A new wetroom bathroom is added to a large bedroom. The only electrics in the bathroom are a 12v extractor fan and a 12v light. The power supplies are both marked SELV and will be housed in the partition wall with an access hatch to the bedroom. The power supplies will be switched using a...

Do you want to block the goverments brain reading waves or perhaps you have a problem with a loud stereo nearby? A copper lined hat may be better for the first, probably best not to discuss the second here. If you can let us know the result you are after......
