    ... I have just learnt another thing ... it is Megohm as the 'a' is dropped when prefixing a measurement beginning with a vowel ... Double Dunce! ;-P

    Protecting armoured cable

    Depends on whether the cable will end up being covered in leaves and other detritus in the longer term ... when it is covered over and the tree surgeon is called in to remove and grind out the stumps ... what then if they miss any remaining signs of a SWA cable?

    Protecting armoured cable

    If a job is worth doing ... I would hire an arbortech allsaw to cut through the roots, dig the trench and bury the cable properly!

    Response taken in good humour, I learn't something new today ... not quite clear on what the middle clause above means.

    ... that said, about Ohm vs ohm, it remains to be seen that in every other usage that I know of it is incorrect to use the short form multiplier of 'M' for Mega with the long form for the thing that we are multiplying ... you never see 'mmetre' in place of millimetre for example. Furthermore...

    Thanks d ... shall I put on the dunce's hat and go and stand in the forum's metaphorical corner? One assumes ... dangerous I know from my earlier foray ... but, nothing ventured nothing gained ... that the full form should be Megaohm like Kilometre.

    ... ohm being the name of a person should read Ohm and therefore M-Ohms or more correctly MOhms surely?

    Drilling Through Copper Bus Bars

    What is a 'water laser'? I have only come across water jet OR laser cutting ... though often companies who do one also do the other! I really don't want to be too pedantic ... I just can't help it ... 'Kevlar matrix' is an interesting term. The Kevlar in a product made from Kevlar is the...

    Extending cables in consumer unit

    ... is that a bit like jiggory pokery? Personally, I take offence at that misuse of the term for a very capable craftsman who would turn out many hundreds of turned chair legs each day, products that if used carefully might last a lifetime or two! ;-P

    I didn't have no 6 mm² so I put in 2 x 2.5 mm² ... it'll do won't it?

    Ring main help

    What would 'work out cheaper'? ... and would it? It is interesting how we all scramble over each other to help one moment, and the next suck our teeth and say get an expert in. Besides which, in my experience consultants borrow your watch to tell you the time and often charge an exorbitant...

    Lollipop circuit on a 40A RCBO

    ... that said, I think that I am correct in saying that the CCC of a cable is related to the heating effect of the power dissipated due to its resistance exceeding the material property limits of the insulation. That power is given by: P = I² x R However, the effective resistance of a RFC is...

    Lollipop circuit on a 40A RCBO

    I am sorry for causing confusion. M's, concern ... I think was for the 'ring' in 2.5 mm² at the 'head' of the 'lollipop'. The 40 A OCPD provides adequate protection for 'stick' in 6.0 mm² cable if it has an allowable CCC of 54 A. However, the cable at the 'head' will have a much lower CCC...

    Lollipop circuit on a 40A RCBO

    The current carrying capacity of the 6.0 mm², 'stick' of the lollipop is well protected by the 40 A OCPD. How then do you explain the 32 A OCPD of a 2.5 mm² RFC when a single piece of cable may be limited to a CCC of 13.5A? I suspect that in this case, the OCPD should be 'downrated' to 20 A.
