Hi,

Need some advise.

Will be looking for a electrician to re-wire my 3 room resale flat. I will need to replace all the wiring and switches as they are all 30 years old and also add new power and lighting points.

What are the common things done in a re-wiring package?

I know there's

1) Lay and install lighting points, power points

2) Replace switch box

3) SCV point

4) Telephone point

What else are there? Electrical testing? Install light?

Want to know so that at least when I'm quoted by electricians I know they are doing the things that are supposed to be done.

Thanks a lot.

electrical testing is optional item. Install light not only electrician can do it, even handy man can do, only thing is usually it's given to electrician to do for sense of completion. Buying of switch is excluding. if u wanted specific brands, design etc.

If the electrician is licensed, then no need testing.

There is still earth bonding, and LAN points if you want to wire for speedier connection. Also, cooker and heater points.

Hi,

Re-wiring:

1. Remove old wiring and supply/install new electrical cables (1.5mm for lighting, 2.5mm for appliances)

2. Remove and supply/install sockets ( 13Amp for normal appliances, 15Amp for Instant Heaters, 20Amp for Aircon)

3. Remove and supply/install lighting switches

Things to take note:

Aircon and Instant Heaters cannot share circuit breakers with others. They must have their own circuit.

For whole house lighting you would need at least 3 rolls ('m not very sure, depending on your needs) of each of the 1.5mm and 2.5mm three colour cables - Black or Brown, Blue and Green/Yellow. If your electrician bring along only 1 roll each of the colour cables, you have to raise the alarm.

Best is if you could be there when they do the works. Cos I think most, if not some, electricians will only change the sockets. They can move lighting points and socket points without replacing the wiring. You cannot tell whether they really replace the wiring because all are encased within the trunking, and you may not be able to tell the difference between old and new wiring.

If the electrician is licensed, then no need testing.

I asked my contractor about the electrical testing, and he says it will cost around $200 to ask PUB to come down to test and certify.

how common is it for people to ask PUB to come down and test? or can we really skip the testing if the electrician is certified?

also i mean, the electrician himself should already do some kind of testing too right?
