Re: [PSES] Japanese manis leads
Hello, Sato-san. Since mains outlets rarely have PE terminals, is the built-in wiring in homes also just 2-core (no PEC) for 100 V and 3-core (no PEC) for 200 V? Best wishes for a happy and prosperous New Year.

At least for household products, majority of products are Class 0 and some specific products such as cloth washers are Class 0I. Here in Japan, mains outlets in homes rarely have PE terminals. Some products such as air conditioners sometimes rated for 200 V, in that case they often have 3-core mains cords.
