[QUOTE="stuboy, post: 526564, member: 33489"] I remember puzzling over E7 the first time i saw it, but then it dawned on me that i am thick, here's how it works:- Henley blocks on your meter tails split the feed:- One goes to your main DB the other goes via a time switch (100A contactor) to the E7 DB, ie heaters etc. When your meter gets the E7 signal it engages the contactor and switches registers to start recording on your E7 tariff. ALL your electricity used will get charged at the night rate until it switches back off again. In the summer (I'm Western Power) its 1am till 8am for mine! Hope that helps. Stuart [/QUOTE]
