hi guys,
if i have a 13A 240V source, does that mean that i can draw up to 3120Watt? i am calculating if i have sufficient wiring for my ceiling lights. Someone told me each wire can only support up to 6 LED lights but i am skeptical... |

QUOTE(ozak @ Aug 8 2018, 09:46 AM) For light, MCB is only 6A. More than that, it will trip. Thats 1440W, even with some contingency i think still more than enough for 10 LED downlights of 20W. Correct?But that is more than enough for your whole house light in 1 point.  |

hi guys,
i'm planning for my house reno and been reading on this thread. Regarding the wiring, what does it mean looping and new wiring? If i already have existing lighting point and i need to connect to 4 downlights? is this consider looping for 4 lights? I have not engage my electrician yet, still doing my own homework at the moment... |

hi guys,
i have a question on how to pull wiring across structural beam. I am planning to install plaster ceiling at the same level as the structural beam for my ground floor. There are some new cables/ wires/ LAN that I need to pull across the structural beam to loop lightings, new outlet, LAN connection etc. I understand that drilling a hole through the structural beam is not advisable, normally how would the electrician pull the cable through structural beam without damaging the beam? Refer to the picture for info... Attached thumbnail(s)

QUOTE(kirakun @ Nov 12 2018, 04:18 PM) Lower your plaster ceiling. All u need is a clearance of around an inch aka 25mm for the wiring and cables to pass through under the beam. Don't think an inch lower will do much to the ceiling height clearance. thanks, thought of that too, every inch is important for me now as i trying to avoid having a pelmet for my aircon  |
