I'm an electronics hobbyist who's learning from wiring stuff together and searching the internet if something doesn't work. Hence my electronics knowledge is very patchy.
I recently found out that mains voltage cables (in my case 230 VAC) should not be run parallel to data cables, because that could cause interference and voltage spikes in the data signals caused by induction.
I'm working on a project right now, where I made exactly that mistake - lucky me that I didn't power it on with the data cables connected to the Raspberry Pi yet.
So now to my questions:
- How far do I need to place the power cables away from the data cables?
- Two power supply PCBs are rather close to the data cables as well (ca. 8 cm & 2 cm).
Could those become a problem?
- Is it possible to damage the Raspberry Pi because of voltage spikes from the data cables caused by mains cables running parallel to them?
- The mains cables are very close to the metal chassis (which is grounded). Could voltage spikes be introduced to the chassis and travel to the data lines even though the mains cables have been moved? (Forgive me if that's a dumb question.)
- A cable powering two 75 W light bulbs runs over the data lines. Could that be a problem?
