More than that, there are laws (at least in Australia) about how data cables must be run.
Similar to how close an electrical outlet can be to a sink, there are rules about how close a data cable can be to a current-carrying cable.
In the UK CBus have CAT5 cable that's rates for installation alongside mains cables (back of lightswitches etc) https://www.cbusdirect.co.uk/cbus-product-range/cbus-cable-a...

The low voltage in the house is completely separated. The wall outlets are widely spaced. It even comes into the house in a different location and a different trench.
> Any good electrician knows you can’t run power and data in the same conduit or pathway. NEC requires a divider in any junction box that contains low-voltage and line-voltage power, and also requires separate conduits/pathways for low-voltage and line-voltage power (can’t use the same stud hole to feed both through)
Sure, but aren't those rules for safety purposes and have nothing to do with crosstalk/interference?

Yes. My point is that an electrician who ignores (or isn’t aware of) NEC rules isn’t anyone I’d let near my home’s electrical wiring. Almost all NEC rules are for safety.
You hired a bad electrician. Any good electrician knows you can’t run power and data in the same conduit or pathway. NEC requires a divider in any junction box that contains low-voltage and line-voltage power, and also requires separate conduits/pathways for low-voltage and line-voltage power (can’t use the same stud hole to feed both through)
Spend more money on the electrician, and they’ll be better at their jobs.
Edit: I run electrical work
