So I had my modem replaced last week, 2 in the space of a year and a half.
Now I don't know much about electrics etc so tell me if I'm wrong :P
The BTo engineer that came out plug the old AC plug into the newer modem (they did the same with the first replacement) and left the AC plug that came with this modem in the box..
So today when I unplugged everything, I looked at the old one and new AC plug, the old one was 1.25a and the new one is 1a.
Could this cause the modem to overheat in time if the 1.25a is used instead of the 1a one?
Edit: God my typing is really bad today.

Assuming the voltage on the two PSUs is the same, then No. The PSU will only supply the current that the modem requires.
On the other hand, if the modem requires more than 1a then then the new PSU has the potential to overheat if it has to supply that current, or it's voltage output will drop and cause it to not operate the modem correctly.
I changed it anways, I always prefer to use the adaptor that comes with it + its white, instead of black, so matches the walls :laugh:
I think most people have light coloured walls, few will have black or very dark colours so why does the majority of electrical equipment, i.e. TV's, HiFi, computers and accessories have black cables ? :dunno:
No idea John , electricians mains cabling is grey but why? Is black cheaper than white I wonder.
So that it shows up against the lighter backgrounds?
Well it will show up against lighter backgrounds but is this a desirable feature ? I'd have thought most people would want the cables to be as unobtrusive as possible.
To make it easier to see, so you don't trip over it?
Tripping hazard avoidance? :dunno: Remember, common sense doesn't come into health and safety. ;D
You shouldn't route cables where you can trip over them or if it's unavoidable then use something like this (http://www.ebay.co.uk/itm/Glow-in-the-Dark-Micro-USB-Charger-Sync-Cable-for-Samsung-S3-S4-Note-2-LG-HTC-/321140443454?pt=UK_MobilePhones_MobilePhoneAccesories_MobilePhoneDataCables_JN&hash=item4ac576493e#ht_1020wt_1399).
Carbon Black is added to rubber to make it more durable, it's used as a filler in plastics why not sure but it's anti static?..
Good points but white plastic covered cables are readily available and often used on multi socketed exetension cables.
I think I recall when I was a lad they were all brown if not braided rubber. I think it's for uniformity of colour with the device and the plug
Silver devices have black plugs also and I have a care unit that's white but has black cabe and plugs. I wonder if its just easier to handle, less prone to discolouration and marks during manufacture. Plugs that come separate like the iMac ones are pale grey. Rubber is not used now either now so cables could be any colour. Maybe it is cheaper for mass production.
