If you put a 15-amp outlet on a 20-amp circuit, you could be risking a fire hazard. This is due to the fact that the breaker protecting that circuit likely won’t shut off until the power drawn from the circuit exceeds 20 amps. Since the outlet is rated for 15 amps, it could overheat and melt, causing the insulation around the wires to melt as well. This, in turn, could ignite surrounding combustible materials and start a fire. However, there are a few things you can do to prevent this from happening:
Use only outlets rated for 20 amps when replacing or installing new electrical outlets
Check the labeling on any devices you plug in to make sure they don’t draw more than 15 amps
Install a 15-amp fuse in the circuit at the main electrical panel to make sure that nothing more than 15 amps can be pulled from that outlet
By doing these things, you’ll help ensure that you’re not overloading your electrical system and that you’re reducing your risk of a potentially dangerous electrical fire.
