    Thoughts on overloaded radial?

    Hi OP. The 0.05M/Ohm between L&N won't be the cause of your RCD tripping mate. Are you 100% sure you disconnected all the loads? Did you do any other tests?

    Offshore/Drillships agencies that take on without offshore experience?

    Most sparks, myself included would not know the answer to this. I'm not sure if we have any members on here who have done off shore work. Sensibly, contact an agency that supplies off shore labour, they should be able to assist with letting you know what is required as you are paying for...

    UK Does this need replacing

    Good plan, Nice one.

    Hello I work for a company in the UK and have done for 15 years, as of this year I’ve been told the following.....

    Isn't it just the £48 for the ECS H&S and £36 for the card. The firm should pay for ECS if they want it. The firm I work for don't give a ---- about them so I pay for my own...

    UK Does this need replacing

    Yes, definitely. That supply cut out is their property and responsibility to maintain.

    Max demand & diversity advice needed

    At the end of the day .......the DNO's BS88 will have the final say lol. That's real world diversity. For the record, I've never seen one blow from overload and I've seen commercial places that you would not believe we're on a 80A BS88 supply fuse. Install a TPN DB with single phase kit. Then...

    JIB Electrotechnical Certification Scheme (ECS) ECS application says grade is unsupported eventhough I have my certs?

    I have just had a re read of your post and a look on ECS site. You meet the criteria for labourer obviously but the reason they are asking is because if you had a sponsoring employer and we're on track for NVQ3 and AM2, then you meet the criteria for Stage 3 Trainee Electrician. Electrical...

    JIB Electrotechnical Certification Scheme (ECS) ECS application says grade is unsupported eventhough I have my certs?

    I'd say you are over qualified for that grade surely. Electrical Improver I would have thought??

    Zs and parallel paths...

    The parallel paths (if there is any) will decrease the loop impedance. A good easy example of where this happens is if you installed a new radial circuit to a boiler. Your R1+ R2 tests would give you a value and you would add this to Ze to give you an expected value for Zs. Later when...

    Electrical assignment Help ??

    OP, as already said, have a go at it and then post your answer, people will help then. You might know more than you think you do. Don't feel too bad either, I know "Electricians" who would be embarrasingly stuffed with that paper, The joke is, in my experience, half the so called sparks in the...

    Am2 testing: Fault finding

    I wasn't criticising you so I apologise if you feel that. If you are not "To the book" as you say, with terminology, then that is just something you can work on. I agree, practicality is important, but practicality and correct terminology is even better. We are all learning all the time. Also...

    Am2 testing: Fault finding

    Yeah, I know mate. Loads of people do incorrectly call them that. Same as people who talk about "earth bonding conductors". I heard a QS actually say that lol

    Am2 testing: Fault finding

    Yes, most colleges do I'm sure. No such thing as a main earth. That could be confusing for someone. The conductor from the DNO earthing terminal to the main earthing terminal is the earthing conductor. Ze is the Earth Fault Loop impedance measured at the origin of the installation.

    Volt meter reading 760volts in 3phase dol starter overloads

    Absolutely amazing Marconi. You are such an asset to this forum. I don't wear hats but if I did, I'd take my hat off to you!!

    Socket feeding DB

    underpinning knowledge questions

    Not much of a course tbh, the training provider you have paid should be guiding you with this

    Wireless/ App switching.... what do you recommend

    If you utilise the cheap wifi controllers to switch your loads via contactors you won't have any prob. Make up little control panels yourself.

    Pete's Videos How not to install and A/C UNIT

    Cars are R134a generally. Splits are 410a or R32 more popular now as lower gwp. It's all very expensive now though!!

    Pete's Videos How not to install and A/C UNIT

    Agreed. Apart from the excess suction and discharge pipework, it seemed fine. A lot neater than a lot of the splits I see around and about. I guess the evaporator and lines are pre vacuumed and the refrigerant in condensor pumped down ready. Just connect the lines and let it go!

    WWYDITS..... What Would You Do In This Situation

    Mate, after what he did to you, I would have no hesitation in doing everything in my arsenal to ensure that he did not get the job, no hesitation whatsoever and I would want him to know it was me too. But I'm like that lol
