Hello All,
I am new here and I don't know if I'm posting in the correct place but I need some help with wiring up my Thyristor.

I have added below a photo of my thyristor.

I don't know why, but I cannot get it to work as a switch.

I will be running the gate off around 1.4v DC and I need to be able to switch around 400v DC.

I am simply trying to use it to switch off and on a 400v DC supply.

Any answers would be much appreciated!

Hi everyone,



I bought a new Bosch 16RE impact drill & have found the noise it makes at low rpms to be unusual. I was unable to upload the video directly here since I kept getting an error I need to contact admin. I've tried to embed the link but the site seems to have an issue, it can share the embedded link I have recorded it & uploaded it to vimeo & shared it here so that you can tell me whether it is normal or something is wrong with it:-

Wondering if this Heathrow thing it outside state actors like the ones with Paris Olympics or whatever it was that was on. Winter Olympics? Para? Can't remember.

Could a sub stations blow up and bellow orange smoke from it?

Seems fishy. Thought I'd ask the lads who would know.

We are Hospital Engineers Based in the USA doing work in Africa. We often use the UK standards & regs as a basis for design. We are trying to better understand the use of RCBO and RCD's in clinical settings for sockets. We are concerned about nuisance trip in critical care situations. We would appreciate both interpretation of the regulations and practical advice from electricians who regular work in Hospitals. Thank you.

Hi would love to hear your take on this, the exact comments taken from a EICR (2014 installation new build-last EICR test Minimal remedials-broken switch rockers/SKTS etc) - this has been repeated several times over a few DB's The comments vary between 100% and 80% of tabulated ZS values. I won't say anymore I will just let you comment yes it was all in Capitals! - ADEQUACY OF PROTECTIVE DEVICES:TYPE AND RATED CURRENT FOR FAULT PROTECTION - ZS EXCEEDS 80% OF TABULATED VALUE WHEN TESTED.

Hello all

I am looking to start a solar and battery storage company for domestic properties.

My background is in industrial electrical work(12 years). I have a 4 year advanced engineering apprenticeship in electrical maintenance and a HNC in Electrical and electronic engineering.

My question is to move over to installing solar and battery storage in domestic properties is there a bridging course which will allow me to gain accreditation? I believe I will need my Part P to be able to...

 

Hello. Just a quick question, when using RCBOs in a TT system does the max permitted Zs change? For example the max permitted Zs for a 32a type c RCBO in a TN system is 0.68, does this change to 1667 in a TT system?

A little about myself first. After doing a physics degree I began working in the battery backup industry designing, testing and building prototype battery backup systems for the telecoms and oil industries. I then worked for a company building switch gear for the rail industry where I qualified 16th edition in 1992. I then rapidly moved into IT and since then barely touched electrics other than the odd commando socket or pat tests. So my experience is dated and limited to mainly industrial...

 

I have been asked to rewire an antique metal standard lamp. It has been rewired previously, but not earthed..! One of the screws on the base has a short length of uninsulated wire attached, presumably from the original earthing.

Unfortunately there is insufficient space to run an extra earth wire from the lamp holder down to the base, which seems to leave me with the option of breaking into the flex at the base and using some form of junction box although it’s difficult to imagine that’s...

 

Just carrying out an EICR on a farm (!!) with a number of DBs spread in a fashion more similar to a hand grenade then any logical approach.

This one took my interest the most as from the supplying DB (3PN) the installer has run a 3C SWA from two separate C curve 32A 60898 MCBs. Earthing is TT. This runs into an old 17th RCCB board.

Its not a split load board.

They then have one phase running to a 2mod 32A RCBO which supplies an adjacent building and the other phase to an RCCB which...

 

Hi, I am not an electrician, just an interested amateur, but I am having problems with a Manrose extractor and I feel I might be getting fobbed off by the manufacturer.
I could smell a burning smell in my ensuite and narrowed it down to the Manrose extractor. I took the cover off and the circuit board cover and could see the plastic had browned and started to melt where it was next to the resistor.
I contacted Manrose and they said it was perfectly normal as the resistor gets hot! I was...

 

Good afternoon everyone, I am Alex and I'm new here.

I am posting this to ask for advice with how I should approach this situation.

We called in an electrician, and as confirmed in writing by messages, the original request was to change the socket covers and change lightbulbs through the flat (1 bedroom flat). After completing the job, the electrician sends us an invoice which lists the labour and material costs, and a rough breakdown of the works done. The final bill is OVER £2,000...

 

Hi I have 2 questions with reagards routes to becoming UK qualified electrician I'm hoping you can help with

1) What's the difference between electricians mate and improver and when are you qualified for this role. is it after Level 2 or level 3 qualifications ?

2) If you are doing C and G 5357 electrical apprenticeship and are made redundant in 4th year but cannot find new employer can the theory units be used from level 3 to qualify via another route - i.e take portfolio and AM2...

Hi All

I have an issue with my shower and I suspect it's the solenoid.
The original fault is that the shower either wouldn't switch on at all, or it very briefly powers on, see video


I removed the front panel and as you can see below, manually pressing the plastic arm starts the water flowing, and it is heated too (i know the danger of using the shower in that state whilst live) so there is no issue with power reaching the unit.


I suspect that the faulty part is the solenoid, but is the...
