Contoversial - but the only way to be 100% sure etc in an inspection is to test everything - which is all sockets all lights floorboards up, knowing the routing of concealed wires etc. Cheaper to rip out and start again. A high percentage of the system can be hit quickly at the CU with...

Earlier this year, a group of bikers were riding out when they saw a girl about to jump off the Humber Bridge . So they stopped. George, their leader, a big burly man of 53, gets off his Harley, walks through a group of gawkers, past the Policeman who was trying to talk her down off the...

If so my son has got problems with both economy 7 and burglar alarms in a charity project house - and is getting ripped off £70.00/hr by the alarm company who maintain the system once a year. Too far for me as I'm in Cornwall but if you feel you could take on the job PM me and I'll forward your...

Isn't it brilliant what you get involved with as an electrician!

Probable too late - but if it's like one I inspected a couple of years ago the heating element was enclosed in a wonderful machined perspex enclosure and the on/off switch was a voltage operated trip with a string passed through the switch lever. No interlock so water had to be on before...

I had a similar problem - but in this case the earthing and bonding was fine.However the washing machine had been operated without the waste pipe connected and although the top of the vinyl flooring was dry to touch it was swimming below - and the contaminated water had come in contact with the...

One thing I've found is that a really good drill bit will make a 50 cheap drill work 10 times better!  I like the Bosch Multipurpose and the De Walt Extreme bits.

Of course - but Zs at a light fitting? I've never seen a recommend that all other circuits should be off. Must try a Zs test at a cooker panel with the cooker on full and off to see if there is a difference.

On an Icon fan I've found that using the dimmer output on the switched live is enough to get the fan working. Reasonable - as the dimmer effectively chops up the waveform to reduce the power - so the peak voltage doesn't get reduced that much until the light is really dim. On another fan I had...

L-E using that method is fine - with everything in the system the earth current should be negligible so the reading will be accurate. L-N - anything in the system could be drawing current - so now you have 2 unknowns - Zs and the parallel impedance. In other words the applied load is now not...

From the lack of replies I obviously do! Been watching too much of The Big Bang Theory!

Sounds a stupid question but even forgetting about RCD's I can't get my head around this. I assume the measurement is derived from a sequence of tests where voltage is measured on no load (so v = line voltage) and then voltage is measured under load (L-E load) so it is like a potential divider...

Sorry - C***** up the attachment - if that is the right choice of words!

Liked this one!

It happened at a New York Airport. This is hilarious. I wish I had the guts of this girl. An award should go to the United Airlines gate agent in New York for being smart and funny, while making her point, when confronted with a passenger who probably deserved to fly as cargo. For all of you out...

Not enough detail to comment. Loft boarded? Stuff to move? Access? Type of accessories? RCD outside socket or not? Sounds like it could be a good days work - so may be underpriced.

I was talking to a British Gas electrician at a job the other day (he was doing a vehicle charging point whilst I was doing outside lights) and he reckons that British Gas now exclusively use Proteus boards as they have upped their game and I assume there is a discount for British Gas. He...

Even more tight fisted - use ext lead at handy socket with earth connected through to MFT nulled at MET. Cost £0.00!!!

Devils advocate here - Re R2 and bonding - can see what you are getting at - but isn't this the same point if you were measuring Zs direct - which a lot of electricians consider the superior test? Regarding furthest accessory - yes agree in principal - but with 10-15 ceiling spots and...
