1. You need to consider the creepage and clearance distances required for you mains voltage. 2. You also need to work out what current is flowing in that track and then decide what temperature rise above ambient is acceptable for that track.  3. Then use tables or an online calculator to work out what track width you need to stay below that temperature rise.  4. If you cannot accommodate the width then you must either got to 2oz copper or use copper on more layers.

Hi! When dealing with AC mains, it is vital to separate AC mains from the low voltage DC side. Clearance, creepage and making isolation slots are a key to make a safe PCB where you can wire your mains in without fearing that you burn your house down :-) -Markus

@andyfierman Hi, I am working on a similar product. Is there a feature in EasyEDA to check for Creepage. I can see that the clearance can be checked with the DRC feature but couldn't find anything for Creepage.

@sbatraAmolvo, Welcome to EasyEDA. There are no built-in tools in EasyEDA to check creepage distance. In fact the Clearance that EasyEDA checks in the DRC and Design Manager are not the same as those for high voltage clearance because they do not take into account the effects of solder mask. Clearance in EasyEDA is purely straight line copper to copper clearance and must be set by the user after consulting suitable external sources of information, such as the links above, to set a suitable clearance taking into account board finish, cleanliness, humidity and altitude.
