Remixed TeachingTechs electronics case to fit [this 30 amp relay](https://www.amazon.com/gp/product/B07DSZFLMQ/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=dlfordio-20&linkId=c8e16d9a4758f5e78cd1d61d7231a9b7&language=en_US) *(affiliate link)*. The 10 amp relays work fine if you're switching power on the A/C line in side, but if you want to power a Pi on a DC to DC buck converter you need to put the relay on the 24VDC line, and you need a 30 amp relay for that.
