Lighting Planning Consultation
Hello. I plan to draw up a lighting scheme (LED spotlights in a suspended ceiling). The following questions arose:
- When designing, you need to design the cabling from the shield to the junction box in the room?
- Do you still need to design the number of wires to each lamp from the junction box or do the wires come with the lamp?
- If you need to design wires, then how to correctly calculate the length of the necessary wires for spotlights?
- Are there LED spotlights powered by 220 V or are they all or 24 (12) V ?.
1. Yes, you need to plan the cabling from the shield to the junction box in the room. In this case, the relative placement of the fixtures (if it will be necessary to distribute power from the box to the 220 V fixtures), the place of the proposed installation of a step-down transformer (if there will be 12 or 24 V fixtures), the location of the light switch should be taken into account.
2. Usually the wires do not come with the fixtures, but in any case, you specify this when purchasing fixtures, if necessary, get the necessary length of the wire.
3. The length of the wire is determined when designing the wiring, taking into account the location of all the lamps, the location of the junction box from which they will be connected, or the location of the step-down transformer if you connect low-voltage lamps. That is, you need to calculate the length of the wire from each lamp to the intended installation location of the junction box or transformer.
When calculating the length of each wire, make a small margin at both ends, which will be needed to connect the cable, and a margin is needed in case you need to reconnect the wire so as not to lay a new cable.
4. There are low-voltage lamps, there are also 220 V.
