if the breadboard test goes through, how much weight copper would be ideal for a single sided copper clad board where a trace for AC mains is used. The load will be an MOT. The layout is show below.
Hi,
Normally trace sizes are based mostly on the current handling requirement. In a device that handles AC from the mains you should have a fuse inline and that will have a rating that will specify how much current will be allowed to go though the traces. From there you can calculate the required trace width. If you do not have such a fuse they you really should base it on your areas electrical outlet specification max. For example in most parts of the US the max is 20 amps for a regular home circuit. For an industrial application it could be much higher though and a fuse would really be mandatory. In fact, i would not build a device that connects directly to the mains without a fuse no matter where it was to be used.
