Adding New Wall Power Socket

[larrytanjj 0]

I mainly working on my desk a lot. My whole desk is powered using two power strip (8 and 5 socket) daisy chain. I know daisy chain power strip is dangerous and I have read about it. The wall socket that is nearest to my desk only have two sockets. one I use it for my desk and the other I use it for shelf rack that use for charging my electronic devices. I do not wan so many device on my desk charging that why I build a shelf nearer to the wall socket. I do not wan to daisy chain my power strip as I on it 24/7 for some hosting reason. I want both power strip to be connected directly to the wall outlet but I have only two socket and I need at least 3. I safely take a peak at the wiring inside the wall socket. it consist of 6 wires. I was thinking of asking some electrician to use just 3 wire for my current wall socket and the other 3 for the newly installed wall socket (2 socket). So total I will have 4 sockets. My worry is the power different between 6 and 3 wire. The following are the device on my desk for your estimation

-Speaker Amp (spec mention was about 350W)

-Small audio equipment 12w~

-DAC 12~

-Xbox

-NAS (consumer grade)

-Access Point (consumer grade)

-Switch (consumer grade)

-23in monitor

-2x laptop with 90w adapter

On my calculation is was about peak and to be safe lets say 900W~

The reason for adding the new socket is I do not want to daisy chain the power strip. I am wonder is this possible to be done and what are the thing that I need to take note of. Thanks alot! =)

If I understood your post correctly...

Inside a power socket, as you have peaked, have 3 wires, one red, one blue and one brown (Live, Neutral, and Earth). When you see 6 wires means they are for two sets of sockets(or just placed inside because there's an extra set). An electrician would be able to connect another set of wire to your existing socket to create another set of socket, or use the exiting set to create another socket. You can basically create a few others but the safety amount, I'm not so sure. Judging from your items... those are pretty normal for work desks. I don't think you will have any issue.

Don't trust what I said, learnt from my electrician hahaha. Better to call an electrician down to see. If you want PM me for contact bah. Since it'll be better if you call him and ask him directly.

HDB power sockets are wired in ring circuit from a 13A rated circuit breaker in the DB box. There are a few rings in one hdb flat unit.

Each ring circuit can support up to approx. 3000W of load. It's quite safe to use those socket for general devices such as desktop LED/fluorescent lamp, handphone chargers, laptop, HIFI system (unless you play vacuum tube amps that consume high current), etc. You may utilise the additional 3 wires (assuming that those 3 wires are the extension from one of the current socket) for a 3rd power socket, but it's not advisable to daisy chain it to a 4th socket.

In fact, the existing 2 sockets are sufficient based on your usage. Just need to buy a good quality fused power strips, and connect each of them separately to each wall socket.

If you don't have any electrical know-how, then better leave this to the licensed electrician. It's no fun to trip the whole house that may damage your other expensive household appliances, or get yourself electrocuted.
