Items in accordance with Standard NBR-5410: 9.5.2.1.2 When determining lighting loads, as an alternative to the application of ABNT NBR 5413, as prescribed in paragraph a) of 4.2.1.2.2, the following criteria may be adopted : a) in rooms or dependencies with an area equal to or less than 6 m2, a minimum load of 100 VA must be provided; b) in a room or premises with an area greater than 6 m2, a minimum load of 100 VA must be provided for the first 6 m2, plus 60 VA for each increase of 4 m2. Table 47 — Minimum conductor section: Lighting circuits: Minimum conductor section mm2 - material: 1.5 Cu and 16 Al Guys, in this video we made a 3D floor plan to simulate a lighting circuit for a residence, with the conduits , switches and junction boxes. All lighting points are on the same circuit and we identify it as circuit “1”. The letters indicate the circuit of each switch. For a 100 Watt incandescent bulb we have 15 W for an LED bulb, that is, the same luminosity capacity while consuming much less. Personally, this incandescent power for LEDs may vary depending on the manufacturer.
