Which wire is hot on a 2 prong plug?
The neutral is the hot for a two-prong plug. The neutral is connected to the ribbed conductor and the hot is connected to the non-ribbed conductor.
Which side of a two prong plug is positive?
Because we use A/C current, prongs don’t have have a positive and negative. Instead, the two prongs have a ‘hot’ and ‘neutral’ side. The wider prong connects to the neutral wire and the smaller prong smaller prong is the hot side of the circuit.
Do you need an electrician to change a plug socket?

Is it OK to leave a broken prong in an outlet?
3 Answers. It could be bad if other things go wrong as well, or if the circuit/device is miswired. It also prevents you from plugging in other grounded devices, which could be a problem as well. The best thing to do would be to either remove it, or replace the receptacle.
Can you use a plug without the top pin?
Without the Earth pin attached, you won’t be able to get the plug into a shuttered socket and why faff around anyway for the sake of a new plug – just doesn’t make sense (unless there is a good reason why you can’t simply change plug) ? Yes, it’s plastic pin.

Can you put a 3 prong outlet without ground?
However, most newer appliances require an outlet that has three prongs for it to be plugged in. This has led many homeowners to incorrectly install a three prong outlet without properly attaching a ground wire. This can lead to many problems including risk of shock and appliances suffering from power surges.
Are 2-prong to 3 prong adapters Safe?
2-3 prong adapters can be safe if grounded and used properly, however, they might not provide the best function. Removing the ground pin from an adapter or using ungrounded outlets can lead to a fire, shock, or even worse.
What happens if the ground prong broke off?
It is not safe to cut the ground prong. Ever. Here’s why: A ground prong creates an emergency path for electricity to travel through if a short circuit or fault happens within the device. If one of these wires breaks or becomes dislodged, the electrical current won’t flow correctly though the device.
What happens if ground wire is not connected?
The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. In the absence of the ground wire, shock hazard conditions will often not cause the breaker to trip unless the circuit has a ground fault interrupter in it.
What happens if you remove the third prong?
When you plug in a three-pronged plug, that third prong is providing an alternate pathway for electricity in the event of a fault. If you cut the third prong off of a plug, you defeat the safety feature. Also, adapters were designed to use the cover screw to complete a ground circuit on some older plug designs.
