    Runpotec XB300 cable dispenser / runposticks / thread size

    Thinking of getting a Runpotec XB300 cable dispenser, as my yellow framed tripod thing is unsatisfactory for all the usual reasons. You can screw in a "Runpostick" (Runpotec's version of super rods) to extend the stubby little mandrel so you can put several drums on (e.g. singles for conduit)...

    Long cable rods

    We might need to pull a cable through around 100m of fairly wide duct (around 10cm) and it might not have an existing draw rope. It has a 28mm water pipe and CAT-5 network cable in there, so one option might be to use the cable as a sacrificial means of pulling a rope and another cable through...

    PAT IR fail on old cooker with rods not cable

    I am PAT testing a very old 2100W Belling tabletop cooker that the customer is keen to keep & paying me to repair. It fails a L-E or N-E IR test at 0.46 M ohms. Internally the cooker uses bare rods rather than cable. I replaced the old cable & plug and L-N I get > 1999, but L-E or N-E still...

    Extending earth rods making minimal difference?

    Today I found a 466 ohm Ze. That's actually a new upper record for me. I assume the rod was completely corroded through. So started to bang in some new 5/8ths rods. 1 rod - 180 ohms. 2 rods - 95 ohms. 3 rods - 93 ohms. Hmm. 4 rods - 92 ohms! Grrrrr. I gave up then as I'd run out of rods. I...

    UK Installing earth rods should be totally buried

    I read a couple of references to ground rods and both stated that they must be buried in the ground but one said 3 inches visible and the other said less than 12 inches visible. I thought they had to be fully buried and even covered . Please confirm I’m correct z(for once!)

    Earth Rods - pointy one

    I need to buy a 5/8 earth rod. Picked one up from my local wholesaler, but it’s threaded both ends. It appears my wholesaler only stocks the 5/8 in an extendable version. I’ve seen online ones with a pointed end, are they readily available, i.e. pointed one end thread the other? Screwfix only...

    Earth Rods in TN-C-S and TN-S

    Why aren't earth rods required on a TN-C-S or TN-S supply? In the US earth rods are mandatory for both. Two earth rods if the first one is over 25 ohms. Here is how its typically done: View: #6 copper (13.3mm2) is run from the neutral bar of the first...

    The hoary old topic of PME, TN-C-S and earthing rods (not TT)

    Somewhere along the line I picked up a suggestion from a forum posting or two that the DNO does not like you to connect an earthing rod to his "earth" - even though it is effectively just creating yet another, local to your installation, earthing point for the multiple ones already assumed to...

The out building is fed via 30ma and cable enclosed in steel conduit which seems to provide the earth in outbuilding so earth loop...

    What Rods should read

    Here is what a rod should read and what our old friend E54 advocates. Fair enough it is not a single rod but 15 19mm dia x 1800mm length rods in a network around the building all joined by a 70mm conductor. So a bit expensive and also would pay havoc in Mr Browns raised flower beds!!! It is a...

    Planters over lightning earth rods

    A client of mine has asked me if it is acceptable to build planters over the lighting earth rods around his building. I told him that as I have never installed nor tested/inspected a lightning system he should seek guidance elsewhere. However common sense says that if there is a facility to...
