Salon issues

[Richterfan]

I walked into a hair salon and they had asked me a question. They have multiple hair stations and when someone is using a hair dryer and another station shuts off their clippers or turns them on it trips the factory gfi on the hair dryer.
I assume it’s due to the shared neutral but all the stations have their own circuit.
You think putting in a gfi would stop the interference caused that gets to the factory gfi?

You are saying that the handheld hair dryer lcdi plug is tripping when someone else turns on Or off a pair of Clippers? Those should not be susceptible to any sort of upstream or line side issues. I do not think that any GFI outlet or breaker is going to fix or resolve what sounds like an equipment issue. I would think either the clippers or the hair dryer is faulty and needs to be replaced. Playing around, I mean experimenting, with different combinations of clippers and dryers turning on and off should isolate the problem appliance.

About the only common line side issues are RF interference and inductive kickback.

I can see inductive kickback being something that is likely with typical hair clippers. All that most of them are is a coil and an armature that oscillates in the field of that coil.

Simple thing to maybe try first is a simple plug-in surge arrester, probably in the receptacle the clipper is plugged into. If that does little good plug a second one into the hair dryer receptacle.

Have the identical problem. Some one else has already attempted to mitigate the problem by pulling dedicated neutrals for each station as well as adding an EGC. Pipes are overfilled and inductance is definitely one of many factors. I am very curious if anyone has attempted to use a dedicated surge arrester for each station?
