light switch for 220V circuit?
Hello, I'm upgrading my DC to one that requires 220Volts.
Currently, I use light switches to turn on my DC. When I rewire, is it safe to use 20A lightswitches on a 220 V line? The switches appear to be rated by amps, but maybe they just assume you are only using 110 .. Thus, I am asking. If it's unsafe, is there a source where I can buy a safe 220V switch (I'm sure the Borg won't carry it). Thanks in advance. |

Hey bf, I hope I am not insulting your intelligence with this comment but the main reason to use a switch rated for 220v is because both leads going in are hot and the double pole/single throw switch isolates both "hots" when when off (or open). And yes, like the others stated, these switches are available from the BORG, at least in my (red)neck of the woods. When you rewire, are you going with your existing wire too? What gauge is that? I can't quote codes but I think 14 gauge might be too small for most 220v motors and their respective current demands. It would not hurt if you ran a larger guage for this machine. (Twelve is a good size) Marc |

Thanks! |
