Hi
Just wanted to ask if anyone has done the basic literacy and Numeracy test that you have to take to gain entrance to the Electrical Installation C&G Level 2 2330? I,m a mature student and hopefully going to be doing this at Barking and Dagenham College this September 2 evenings a week for 3...
Hi,
I have a little thermostat... very basic... ( two metals theory.)
think it was orig a thermostat for a fish tank heater.
Im thinking of putting it into the circuit of a small heater, so it will heat
the greenhouse to 70 , then cut out.
Im wondering, should I wire it into the...
Hi all, Tommorow I have an inspection and testing practicle, Fairly confident in the actual testing part however just a couple of questions for filling in our test sheets
1) Am I correct in thinking you dont need to record a type for an RCD?
2) What should be recorded in the I^N (Braking...
what is meant by the term "basic protection" In relationship to electric shock ? a) contact with parts or conductors that are live under fault conditions. b) contact with parts or conductors that are not intended to be live unless there is a fault. c) contact with parts or conductors that are...
Found this on a large testing companies website:
'Where the mains supply is connected, as will be the case for periodic testing, the protective and equipotential conductors must not be disconnected because if a fault occurs these conductors may rise to a high potential above...
hi guys,
whats the difference between basic and fault protection.
am i right in guessing fault protection is the means of earth were as basic protection is means of instulation of wires, ect
hi guys,
Just need some help with some course work.
does earthing provide basic or fault protection?
Now i know it provides fault protection as the earth is need to trip the circut breakers but im thinking is this a trick question and could it be both? :rolleyes2:
any help is muchly...
Hi guys,
I am interested in learning more about the theory of electricity, and have been looking online for info, but there is one thing that I just cannot get past:
If the voltage (240v) is used to push the current, and the current is amps, and the power is watts, how is the wattage...
basicly the house im living in has an old sky dish, one of those small ones, iv run a ct100 single cable from the dish and used a sky end to connect to it ( one of those you just twist on, ) but to test the signal i but a coax male end on and plugged it direct to my tv,but it says no signal,
can...
Hi all, I think this classes as a "newbie" style question, but any helpful experience gratefully received.
My employer wants to install a CCTV camera at the entrance to the premises, the cable has been run and basically everything's ready to go, but we want to put an isolation point near the...
Hello,
I would like to do a course that gives me a basic understanding of electricity and how it works. I don't want to become an electrician right now but would like any course I do to be useful in the future in case I decide that becoming a qualified electrician might be useful. Could anyone...
Hi all
I am interested in going back to basic,s involving pcb,s..My object is to be able to do basic simple repaire,s to radios, monitors ect. I know the world of pcbs is vast and i want to start at the begining,i am finding it hard to find what ref books to buy or where on the internet to find...
Hi everyone,I have today literally started learning about electrics and have never fitted anything before. We recently built a new piece of furniture next to a double plug socket so had to remove it so the furniture would fit next to the wall. I made a hole in the unit and now need to extend the...
Not totally off-topic I suppose - I'm interested in learning more about electronics and circuit design. I'm currently half way through 2330 Level 3 and really enjoying the electronics element (brief though it is).
I have done some circuit building in the past and know how to identify...
I needed replacement plugs for rechargeable batteries (eg from mobile phone devices) and had heard alot of alarming statements (no pun intended) on general related websites, all telling me to avoid third party adapters that had an incorrect or higher output in voltage or current than what a...
Hi guys
I am not an electrican but theory wise there is no issue thanks to doing electrical and electronic engineering degree. I stated 2330 and got fed up with it (pt), too basic. I did the 16th edition and passed it (some time back) I want to do the 2392-10 before doing the proper 2391 full...
Hello lads. Needing some advice here. Putting together a presentation for my young 2nd stage students. The topic is Earthing and Earth Leakage. At the moment I'm looking for examples of basic protection....especially images. Got some for the "Insulation of live parts", and the "Barriers or...
None of the PV companies I've dealt with so far has been able to explain what, to me, is a basic question. In a property with a grid connection and a PV installation what ensures that the energy from the array is used preferentially to that coming through the utility meter?
