Dear All,
With the recent, ongoing thread on inverters, could I chip in and ask a couple of questions concerning three phase wiring please?
- If wiring up a 4-pin three phase plug/socket, is there an analogous mnemonic to a 240v plug (bLue, left, bRown, right, etc.)? The conductor wires out of my converter are black, blue and brown; the socket is marked L1, L2, L3. At the moment, I have it wired alphabetically (i.e. black-L1)
- On said set-up, how (if at all) can I connect a transformer [440--12v] to power the machine light? As received, the machine had the live of the light connected to one of the phase wires, and a separate (black) neutral (?) wire. As I understand it, this would require three phases plus neutral (5-pin plug) and send 240v into the light. Can I just connect the transformer across any two of the phase wires?
A tip I recently read: when wiring a plug, make the earth wire longer than the others. If the cable pulls out, the earth is the last to 'let go'.
Thanks for any tips.
