Below is an excerpt from NBR-5410/04, which shows the conditions that must be met simultaneously for this type of connection to be made: 9.5.3.3 In residential areas, it is permitted, as an exception to the general rule of 4.2.5.5, that socket points, except those indicated in 9.5.3.2, and lighting points may be powered by a common circuit, provided that the following conditions are simultaneously met: a) the design current (IB) of the common circuit (lighting plus sockets) must not exceed 16 A; b) the lighting points are not supplied, in their entirety, by a single circuit, if this circuit is common (lighting plus sockets); and c) the socket points, excluding those indicated in 9.5.3.2, are not supplied, in their entirety, by a single circuit, if this circuit is common (lighting plus sockets). ===================================== Share this video: ➡️ • How to install a double switch with t... =================================== Subscribe here: ➡️ / Elétricasemmistério ===================================== Instagram: ➡️ / Eletricasemmisterio =================================== #InterruptorDuploComTomada #ElétricaSemMistério
