Does low AC power kill amps?

[MuzikMan]

I'm sorry to hear that buddy. I hope the ops go well for you.

Thanks for the kind words! I feel like I am in good hands at UCONN Medical Center. I am a little concerned about the money thing right now though.

Who or whom are you working for? That borders on malfeasance or at least electrical ignorance.

I choose to not get into a pissing contest about qualifications although I do work for the larget full service residential home remodeling company in the US and also spent a great deal of time designing and building secure power and como installations for the DoD.

Had one of our electrican's (has been a master for 12 years) review the above and he disagrees with your position based on my suggestion.

You will find that being respectful will get you much farther in life than mean spirited, narcistic comments. No one here knows everything. Perhaps some day you might need some advice that will not be offered based on your disposition.

Respectfullness is definitely a lost artform. However, I do believe that sometimes people can have good intensions and become passionate about their beliefs and lack the ability to sell their ideas. I sympathise with those people but do recommend that they put some time into improving their disposition. It will help them in the long run.

When the voltage is decreased, the current which can pass the fuse can increase

That is incorrect unless the power supply is of a type that compensates for low input voltage. Most aren't.

Low AC mains voltage will almost always not damage electronics (there might be some weird instances in which it might, so I'll leave that possibility open). But if the voltage sags as much as you describe, then the wiring has some problems, and it's likely that wherever this huge voltage drop is occurring is getting dangerously hot. I think your drummer's house probably has a serious fire hazard.

Some of the cheaper generators produce a square wave of varying frequency.

That would describe some electronic inverters, but not actual generators.

 

[Bob Lee (QSC)]

Electricity always takes the path of least resistance which may be through you if the ground rod is on the other end if the property.

Actually, electricity takes all available paths, not just the one with least resistance. The current through each path will be inversely proportional to the resistance. IOW, more resistance = less current, less resistance = more current.

For example, if you have 120V across two paths--one path is 1Ω and the other is 2Ω--120A of current will flow through the 1Ω path and 60A will flow through the 2Ω one. Until the circuit breaker trips.

 

[Bob Lee (QSC)]

A generator powered by an engine (i.e., diesel or gasoline fueled) will put out a sine wave, and generally quite a clean one at that. The usual drawbacks with them are voltage and frequency instability, but better-quality ones tend to be very good.
