    Design 2396 Project - 2016

    Hi Speeka, Yes brings back of few memories. Not much support for the 2396 compared with the info available for say the 2391, or whatever it is called these days.... One book that I found useful is https://www.amazon.co.uk/IET-Wiring-Regulations-Verification-Installations/dp/1138606006 Seems...

    High Voltage advice (11KV)

    Ask the gaffer for the HV switching plan, permit to work, risk assessment and scope of works. Chances are they will not be forth coming. What brand of RMU and switch gear are installed?

    3 Phase power keeps on tripping

    It sounds like a head scratcher indeed. If it continues to trip, check if there is a Telecom Cabin on the rooftop somewhere. As these are normally full of AC-DC rectifiers and PSUs. Failing that, get the LL to have an Electrical Installation Condition Report on the subs and LL services.

    IT earthing system cable calculation

    Yes , redundancy through out. And yes the VFD board is all DC drilling equipment. You can almost predict when the galley starts preparing meals, as the earth fault alarms ping through when they turn on the grills and hot plates lol!

    Current transformer metering producing implausible readings

    As already mentioned, check the CT ratio is correct. Verify they have not used protection type CTs by mistake as these are normally not suitable for metering! And those secondary connections on the CTs need earthed as well for safety!

    Do hazardous area light fitting need an internal cut off switch when the cover is opened?

    Doubt that there will be anything in the Intrinsically Safe standards about this (60079-11) It would depend on the certification for the fitting to be honest. Any that I have seen like this are rated for Zone 1 use. I believe the diffuser switch technically allows relamping in the Haz Area...

    Can multiple motors share 1 mcb.

    I would have separate TP MCBs or fuses for these lot. A bigger panel required, yes. Siemens or Schneider make the combined mccb / overload units. You would really need to study the automation logic to get a picture of motor running sequence. Likely to be a PLC with Analog inputs closed loop...

    SWA Cable - Identification

    I'll not name names lol! There is three letters in the name, but not C, E or F. First letter is K.... I've no problems with where the cable is made, as long as it is up to the job. Turkey have a market now for recycling old rigs and ships, so guess there is plenty of copper around.

    SWA Cable - Identification

    Certainly looks like 6mm XLPE. Try a 6mm black bootlace on the conductors....... Recently received some Turkish 4C 1.5mm XLPE SWA, needless to say it got a good once over before the delivery driver got my 'signature' on his delivery docket!!
