Hi all
I am in an industrial unit and the 100mA RCCB keeps tripping.
They use it as the main switch inside of the unit's distribution board. The mainboard that feeds all the units has an MCB in it.
The RCCB keeps tripping when I plug-in AC to DC transformer loads such as laptops, speakers...
I make my own ceeform adaptor leads for testing purposes where the 4mm banana leads generally just get plugged into my own MFT which is all internally fused. All ratings and sizes - 16/1 up to 125/3
However, it's occurred to me that technically that's not compliant to GS38 (or certainly not in...
Hello, I am looking to get some din rail terminals what I can put a 500 Ohm Resistor in. In the past I have used ones like in the photo attached, I cant seem to find them online now. Can anyone tell me the correct term to find them on RS or any other supplier. Thanks
Hi,
I've just landed a job as an electrical tester and need a new MFT (mainly light industrial).
As I'm going to be spending considerable time testing I thought I'd ask about the new high-end options.
what are peoples favourites?
Are these new fancy options like Bluetooth on the mergers...
Hi,
I'm an industrial spark and taking my 2391 next week (wish me luck, I need it).
I decided to get a bit of practice and started an inspection on my own house.
I got as far as, b32 socket (ring?!) breaker looks slightly browned, better check it.
3 cables in the breaker two identical and...
Dear Members, My name is Abdulhakim am from kenya, i work with an electrical company by name Link-up Power Engineers dealing with industrial installations, am very glad to join this great group.
Hello I’m a student learning about industrial wiring and circuits and we’re about to start learning about how to do loop impedance calculations. I have made a drawing of a three phase installation and was wondering if anyone could give me information on how I get the Ze Zs and R1 + R2. How would...
Hi guys I have a few questions regarding my findings today and wondering if any of you could help one of the guys asked me to have a look at an electrical panel due to him finding voltage from a 24v PSU + to the earth of the panel and the - to earth each readings were 6vac which I was curious...
I've been watching Residual Current on youtube (great vids and great bloke btw) and really love watching the more industrial/commercial side of things.
Are there any resources that teach how 3 phase works? Even college syllabuses seem to be very light on 3 phase stuff.
How do people learn this...
I brought my industrial automation certificate from Brazil to the UK, I received Btec national diploma/ level 3 extended diploma can I work with this qualification in electrical here in London and which card can I apply? Thanks in advance
Hi guys me and my boss will be doing a complete re new of a farm installation we will be removing the bus bar system and installing a a 3 phase distribution board to supply sub main boards to other locations on the farm with my understanding a would not put a 300mA main switch incase it took out...
Hello all,
I'm surprised how hard it is to find a USB outlet for industrial panels. I've found several small compact converters (I think aimed at vehicles) that give out the correct voltage and low cost but not DIN rail mounted. I was looking for a 24 VDC power supply with a USB (or 3) ports on...
Hi
Trying to sort an argument here, am I right in saying that ALL work including altering existing circuits in commercial and industrial installations requires SPD protection unless a risk assessment is completed.
The only exception would be a direct replacement for maintenance purposes?
Thanks
Hello all.
What do you put down as the next test on a brand new industrial install?
I know the recommended interval between EICR's is 3 years for Industrial and 5 years on domestic EICR's but with installs its normally a 10 year cert.
What do you guys put as the next recommended test date on...
So I have two offers one person does more industrial offices, prisons, university’s etc.
The other guy does more houses and stuff like that. My plans are after my apprenticeship is to go on my own and maybe if I get big enough to get people working for me.
So I was just wondering what’s the...
Morning all.
Long story short been an electrical engineer for 10 years. looking to take on domestic work (and no Ime not claiming it easy or that Ime fully able)
My qualifications include electrical HNC, electrical Maintenance NVQ3. Engineer operations NVQ 2+3. Mechanical BTech. Compex, IOSH...
Hi everyone!
I'm just after some advice regarding the power supply in an industrial unit I am about to lease. Does this unit have a 3 phase supply that I can use? I plan to get an electrician to fit some commercial fan heaters, but can't decide wether or not I already have 3 phase power that...
So I've just recently qualified from my apprenticeship and I'm looking to expand my knowledge on a few different systems such as:
A) CCTV
B) Fire alarm systems
C) Door entry systems
D) Smart systems
E) Industrial equipment
Not working at the moment and not so eager to get back on site so soon...
