An illuminable decoration comprises at least two trunk sections, each trunk section includes a hollow tube and a cable assembly coupled to each trunk section. Each cable assembly comprises a first modular electrical connector end that has an inner socket and an outer plug that circumscribes the inner socket. Further, each cable assembly comprises a second modular electrical connector end that has an inner plug and an outer socket that circumscribes the inner plug. A first electrical wire electrically couples between the inner socket of the first modular electrical connector and the inner plug of the second modular electrical connector. Also, a second electrical wire electrically couples between the outer plug of the first modular electrical connector and the outer socket of the second modular electrical connector. When two trunk sections are assembled together end-to-end, the trunk sections are mechanically and electrically coupled to form a modular electrical distribution system.
