Heater

Featherl

I have a heater under office desk, can sometimes be very cold. I have noticed to plug sprongs have now melted and are black. I also see that the 3 holes I put the plug into are now black (burned) too. Why did this happen? Is it still ok to use?

You have a bad connection in the plug socket. The prongs in the socket which touch off the plug fingers are loose and create heat when the electrical heater is on., or the wiring at the back of the socket is loose.
Discontinue use of this socket and heater and have them professionally checked. You risk creating enough heat in the socket to cause a fire.

Agreed, best bet is to change the heater (remember to bring the old one with you to have it recycled, they have to take it if they are supplying you with a replacement) and have the socket refitted and checked, these heaters use large currents and are on a lot, they are all a bad idea though, and best avoided. If it is your only form of heat you should consider the more expensive oil based electric rads.

Probably a sub-standard socket or plug used initially, or a socket that has experienced a lot of wear.

I would recommend that you change both the wall socket and the appliance plug in this case.
