    Voltage Optimiser adjustment

    So if its putting out 230.7 Volts, we can assume its on the lowest 6% setting. According to what I've read it uses a Toroidal transformer of some sort. Thanks for that info. No problems encountered with Switch Mode power supplies, its her Oven, its obviously taking a longer to get up to temp, I...

    Voltage Optimiser adjustment

    That's what I was wondering, I was contacted by the Company who sold the thing to a gullible elderly Lady, and was asked to visit the home check the Voltage and adjust as required, Out Put from the Eco Max is 230.7 Volts on my calibrated Fluke Meter, so acceptable, but I could not see any...

    Washing machine in Bathroom ?

    Yes I remember Zone 3, I believe that was brought in because of the trend for Bathroom on Suites, so to recap then, you can instal a IPX4 Appliance in a bathroom as long as the FCU is over 600 mm from Zone 0, and the supply for it will not require any Earth leakage protection, to be retro...

    Washing machine in Bathroom ?

    So, if the electrical installation complies with the 17th or 18th and the FCU is more than 600mm from Zone 0, (which it was) its ok. If on the other hand, the installation complies with earlier wiring regs its a no go ? Is that the general synopsis. Thanks for the quick response.

    Washing machine in Bathroom ?

    Just spent a few days renting a Holiday apartment (in England), and was surprised to see a WM installed in a very small Bathroom, further inspection reviled it was wired directly to a switched FCU, and I would also suggest it was located only about 18 inches or 450mm away from the bath. ie Zone...

    History of Electrical supply in France.

    Many thanks for the informed response. The inquiry was in relation to a story that a certain Radio (model PCR) made by the Pye company was distributed amongst French Civilians and I assume also the resistance before the invasion, so they could monitor BBC Radio transmissions, for coded messages...

    History of Electrical supply in France.

    Does anyone know how widespread the 230 Volt AC Supply system was in France during the later War years, 1942 onwards. Or what was the most common domestic voltage and system ? Were there areas of DC, as in the UK ? I cant find any info on the net , any info really appreciated.

    Accurately measuring high frequency AC.

    I have been informed by some one knowledgeable, that the old style AVO 8 Meter with its copper oxide rectifier is accurate up to 100Khz. So its now time to blow the dust of my old AVO 8. Thanks for the replies, I did find some suggested circuits and methods using a DMM on the net, but the...

    Accurately measuring high frequency AC.

    Hope some one can help with this one, strictly not a DIY job, but I have been asked at work to measure a 8 Khz, 650 Volt RMS AC voltage to a accuracy of plus or minus 5 volts. Tried several good quality digital meters but they don't appear to respond accurately to AC of that frequency. Did...

    TWO PHASE MOTOR

    Thanks John, I was beginning to think every thing I learnt in the 70`s was wrong.

    TWO PHASE MOTOR

    OK, I pressed the wrong button, 240v. So what you are stating is that the USA 240V supply is not, as I had previously been informed a two phase supply, but a 120v-0-120v, with both 120`s being in phase, and any 240v appliance or load is connected between. Hence, the need for the start cap. That...

    TWO PHASE MOTOR

    I understand about the 220v 2 phase USA system, however I thought as there is a phase shift in the two supply phases it would not need the cap, but I think what you saying is, as the phase difference would be 180 deg, it then needs a start cap. Incidentally, the Motor has 3 connections...
