I have a pool pump that I recently bought used to replace a failing pump. The motor is rated for either 115v or 230v (low/hi switch) operation.
My previous pump was wired with a 12 gauge line to a L5-20 125V 20A receptacle.
So, I replaced the standard 110v three prong line on the new pump with the 12 gauge line.
Will having the 125v wired into the 115v pump leads cause a problem with the motor?
Meaning, is that additional 10v going to burn out the motor?

1) American house-current power is commonly described as anything from 110VAC to 120VAC.(Similarly, the higher voltage obtained by using both phases is called everything from 220VAC to 240VAC.) I believe this is mostly a historical artifact, and appliances labelled for anything in the respective range should work with any voltage within that range.
2) Fittings are overdesigned slightly for safety. So a receptacle intended for use with American house-current power will typically be rated for 125VAC. That doesn't mean it necessarily supplies 125VAC, only that it's tested and promised to be safe up to that (higher-than-needed) voltage.
