Actually, my price was back in May 2021. The problem I face is the location. The moment they know the address, they have many reasons to raise the price.

Recently, I joined a facebook group (mainly for Mandarin users) and got a few electricians to quote me. The price per light point is only RM 65 - 75 per point and the 13A is only RM 100 per point for the current market price.

I am going to share the quality of the "Data Centre" electrician. He claimed that he has done several data centres. Contract signed is Cat6 wire. Get the foreign labour to lay Cat5e unbranded wire.

These are the quality of the "Data Centre" electrician, not mentioned the light, aircond and fan switches of my living room are put at car porch:

Pendant light point is placed next to the fan.

Cat5e was used despite the contract and pricing is Cat6. Argument is I don't need Cat6 for CCTV. But, price is the same.

Because I said I will use LED light, no Earth line for the points.

My requirement is concealed and this picture shows my bathroom. The network and 13A cables were put like this. Below the sinks. If he forgot to place the PVC conduit during casting of slab, he can hack. But, the electrician refused unless I paid VO price. Like this, can I do water proofing?

For a 60 sen joint that was broken - would you replace a new one or tore a piece of paper and cover the hole?

I have invited several electricians came to inspect and re-quote. Most of them were terrified by the quality and even suggested me to bring in Suruhanjaya Tenaga or CIDB as the foreigners that did the wiring obviously did not have the P4 wireman qualification. 

I have given my main con a dateline to settle this. Otherwise, I will upload the photo the FB groups to share the pains. https://www.facebook.com/groups/155815638381028/about has 121K members and another group https://www.facebook.com/groups/1465699686984899/about has 76K members.

The photo I showed were minimum, I have captured a lot others, e.g. wiring can be done the following:

No T-joint box was fitted

Bedrooms have the following PVC conduit on the floors, to be covered by the 50mm cement rendering. But, my timber installer needed to have 40mm gap between the PVC conduit and the nails. VO price will be applied if I request to hack and embed the conduit into the slab. Prices quoted were supposed to be concealed last year.

Ya, I told my main con that he should go to CIDB.

My main con was hoping to get this Data Centre electrician to rework. I told him, if I ever see unauthorized subcon comes in to work again, I will make a police report for trepassing and I also treat the contract has been terminated by himself.

More photo to share:

Anyone have ideas on how to tidy up this unifi fibre cable? See image

The cable is quite tough itself.

careful with this optic cable.
dont sharp bend.. u'll end up with broken optic cable later.
just slowly curl to big round bundle.
cable tie or velcro tape it nicely and hang somewhere.

In my house all the lighting points have 2 wires connected as one. What’s the reason behind this? Why didn’t the developer just use a higher gauge wire?

what colour the '2' cables?
if black, mostly Neutral looping. this is normal for lighting circuit and some sso (Switch Socket Outlet) circuit.
that looping goes to another end-point/lights/fans
