13. Cable constructions of multiple gauge wires that influence the way high, medium and low frequencies propagate through the power cable.

60Hz, yeah, if all you have connected to the AC power mains in your home are incandescent light bulbs.
Any electronics in your home? Audio system? TVs? Computer/s? Appliances with a micro processor? How about CFL and LED lights? Any fixtures with electronic ballasts? Gas furnace with a blower fan controlled by a VFD? Here in the USA our homes are stuffed full of equipment and appliances that are spewing harmonics back out onto the AC mains. Maybe a lot of it from our audio equipment.
