cu screwdriver - unaware

[tbs1983]

Hi guys, i bought a screwdriver for the terminals in a CU today. Ok you say! but the reason im posting this is because ive been an apprentice then electrician for 8 years now, and only found out such a tool existed recently. I put this down to the fact the guys i learnt from never used them or mentioned they existed, and neither did my college, let alone have any for us to use during practical lessons. Therefore ive always used a pozi screwdriver because thats what i thought u used.

Question 1 - anyone else had same thing?
Question 2 - does proper one make a difference (i dont even know what u call them!)
Question 3 - why aren't colleges educating students about them.

Found the ck to be a bit crap swapped over to wer and seem to be a lot better

Ive used one they are good, but can still get just a tight termination using the right size flat head.....pozi can round off......plus it is just another screwdriver to find/get out the case.

they come in 2 types philips and pozi, and 2 sizes large and small,wera usually do them at toolfair £10 a pair,but if you buy their set in the pouch with the interchangeable handle you get all 4 plus cab keys,4 flats pozi's and philips,they are a great tool but just like pozi and philips screwdrivers you need to use the right modulo bit ie pozi or philips.

Had my +- for about 10 years now. Bought them from RS components. They are "the" screwdriver for most CU/MCB/RCD/RCBO screws. Shame the Wiha don't realise this, as the Torque screwdriver set doesn't include them....

These screwdrivers seem to fit better than the pozi drive i got one as a freebie they are just perfect for tightening rcd terminals & mcbs they do seem to grip better & not so suseptible to camming out when applying pressure. the torque screwdriver i have just purchased has one with it included.

I've used mine for 3 or 4 years now, definitely get a better grip using the correct screwdriver! What worries me a bit is quite a few of the youngsters I see, they've been to college, finished their apprenticeship, but still don't know the difference between pozi and philips.

I use a Klauke + -.ELECSA do them for about £5.Very well made,not much chance of breaking it.

So that begs the question, which type of screwhead do most MCB manufacturers use, Pozi or Phillips? Whilst I know the difference between the two in principal, I've never been able to tell visually, only by using either a PZ or PH driver and seeing which feels the best fit.

Thanks mate. I being a bit dim (killed a load of brain cells last night) but are these mystical MCB / CU etc bits the ones coded PH1 and PH2?

Looking at a philips head it has just two 'grooved' at 90 degrees forming a cross. A pozi head has a smaller, additional 'cross' at 45 degrees to the main one, more like a star.

Cheers, I think I've just been looking at different makes of PZ thinking one is a PH. DOH! What a muppet.

I think you misunderstood me. I was referring to myself as the muppet, not you.
