[QUOTE="TJ Cornish, post: 27591, member: 162"] Re: Electrical safety question (xposted from PSW) There is a distinction between "manufacturer approved/UL approved/best practice" and "works in a qualified sense". The amp is designed with a 30 amp cord because that's what's required to operate the amp to its design specs. They didn't just put that on there to be mean. If you are using this amp in an install situation, get the right 30A service for it. If you are using this amp in a portable situation where 30A service won't be available, you can build an adapter cord as you describe so you can plug the amp into a 20A circuit. You won't burn anything up or damage the amp, but you risk blowing the breaker when running the amp hard. Using an adapter may be preferable to replacing the amp's plug in that you won't void the warranty by modifying the amp. By the way, this isn't OK in the reverse direction - you can't safely make an adapter providing a 20A receptacle from a 30A circuit without also providing 20A overcurrent protection. [/QUOTE]
