What torque bit.... Contactum rcbo

[sythai]

Hi Chaps

I've got a Wiha torque driver but only came with couple of bits (below)... none of which fit 'outgoing side' of Contactum RCBO's.

Anyone know what size I'd need please ? So can order up

Tried their technical but no one there until next week

Cheers Sy

If those aren't fitting correctly, it may be SL/PH1 or SL/PH2

Markings on the screw heads should indicate whether it is Pozi or Philips.

definably has the markings of pozi.... but the PZ1 is too small and PZ2 is too big

I tend to just use a 3.5 or 4mm flat

Biggest that will fit.

Not sure what it is but alot of manufacturers RCBOs have strange screw heads. I tend to use a flat head screwdriver in these too.

Is it just a little tight for the SL/PZ2? Maybe the plastic just needs worn away a little?

I’ve got same bits for my wera torque, and not had an issue.
I actually snapped an SL/PZ1 using it in a terminal which I thought the hole was too small for the bigger size.

Been on to Contactum technical..... so need to use PZs1 and PZs2
See if I can find these in Wiha now to fit my driver

So you need a PZ1.5S ?
Something between a 1 and 2

These are the ones.... smaller one for outgoing side

PZs1 and PZs2

Not uncommon to see #1 used on outgoing terminals. Have seen them also used on earth & neutral busbars. Bit of a pain that manufacturers can't use a common head on all terminals.

I wouldn't mind seeing Torx20 used for terminals in a board. Have been fitting hobs and cookers of late which all have Torx20 for connection screws and are lovely. Or just go back to flat head screws

I'd like to see Scrulox on everything.

Lets bring in Robinson screws for terminals.....
