I had a washer and drier on the same FCU for years, and fuse never ruptured, I like the ring due to volt drop restrictions, a ring can have 106 meters of cable max to comply with the 5% volt drop, this assumes 20 amp load at centre and 12 amp even spread.
With the radial the 20 amp is at the...
I am told if a phase is lost with the one where I work it auto closes down. Had a customer query why not charging at 22 kW so wondered if we had lost a phase, and was told no, as it would close down, yet is seems happy to charge cars at 7 kW when the car not wired for three phase.
I was rather surprised to read the pre-1966 regulations.
So you can't use LED lights without an earth even before 1966, and the switches clearly still needed an earth.
The problem has now become worse, with the use of Smart relays, and having the switches switch extra low voltage.
I have found with my own house an intermittent fault with the light switches, the lamp is not easy to access, needs an access platform, so when the light switch failed, I did not...
When I get a chance, I will test my children's homes, and see what they show, it does seem the DC test is a bit hit and miss, the instructions say how it needs zeroing, and it seems my high DC is more down to not zeroing correctly than any fault.
As to imbalance, although high, it is a large...
An I thought this house was bad, I had a home buyers report done, it pointed out a redundant fuse box was wedged between false ceiling and original ceiling, but it was not redundant. I had a fuse box and a consumer unit.
I has a new consumer unit fitted all RCBO's with idea any faults I can...
I did three C&G courses one after the other, 16th edition 6 weeks, PAT testing 6 weeks, installation testing 12 weeks, all night classes and all with C&G, around three hours a week.
However the installation testing was only open to electricians, and the PAT testing open to all, it was just...
I have tried to find out what is required with the EICR, English law I can find, Welsh law coming in 1st December, but the law does not seem to detail what is required, it talks about fit for human habitation, and smoke detectors are required, but wading thought the law I find nothing, only find...
I have used LAP grid system a lot, and it has done what I wanted, I have also had problems with Philips bulbs, and going by own experience I would say Philips bulbs are also a must to avoid. But first is to look at the compatibility chart link is one for my switch, better if you look at the one...
I had same problem, in my case G9 lamps, and a simple on/off electronic switch without a neutral. the small lamp shown came with the chandelier, replacing one with a quartz lamp stopped the flicker, however whole idea was to go LED, we looked at the published list of bulbs which should work, but...
Electronic switches, be it simple on/off or dimming have problems with LED lights, the problem is an LED is a DC device and runs on around 5 volt, so inside the bulb there is a driver that converts 230 volt AC to the current required by the LED and there are loads of methods used to do this.
So...
Must admit I don't know exactly how it all works, the willis immersion heater is clearly different from direct, and going in from side of tank is also different from going in from top, but it seems unlikely that all thermostats work in the same way.
We would around every three months do the in service inspecting and testing of electrical equipment on our batching plant, no question it was potable it was moved as 22 articulated wagon loads, and the trailer wheels remained attached, it would take three electricians two days (the week end) to...
Had it with a WMDU (weather proof main distribution unit) first few times we blamed some one not torque them to correct torque, but had repeated cases, seems the bus bars were copper coated aluminium and heating and cooling caused the connections to become loose.
Some times it was current...
We have always had prosecutions for work without a warranty of skill being unsafe, but as yet not seen one for listing items which really should not be coded as Code C2.
My son worked for a firm doing inspecting and testing back around 2005 he did not do it for long, and he was told always find...
