Yes, as long as the electrical wiring is made of copper and in reasonably good condition it will send data just fine. Powerline adapters rely on the electrical wiring of a house in order to work. Generally speaking, this will function just fine unless there's another problem with the wiring at hand. Copper is most commonly used for making powerlines and it should be able to send data if in reasonable condition though that might not always be true depending on other factors involved so keep an eye out!
