100v,115v versus 230v

@ sabih hi i live in the U.S.A. state of (RI)

@ditusa , please do excuse my lack of understanding is rhode island ac mains 230 volt ? because my understanding from your earlier post as if you were running your gear 230 volt and you are preferring it this way, could you educate me how do you do it ? much appreciate your help. moving to Bangor (Maine)

I’m moving to USA soon ,planning to take all my gear with me do not want sell my we91 amplifier which is 240 volt that’s why raise the question , in my humble opinion audio equipment regardless of how hungry or not performs better 240 volt operation.

I doubt any audio equipment designer/manufacturers would agree with you that feeding their equipment 240Vac is better than 120Vac for the sound from their audio equipment.


UK power.

The power system in the UK used in residential housing would not meet electrical safety codes in the US.

The UK power system is a grounded "Power System". It has a Grounded Conductor, Neutral Conductor, and an "Ungrounded Conductor", the Hot Conductor. How and where the service neutral conductor is connected to mother earth in the UK is different than where it is connected to earth here in the US, from what I understand.

Residential electrical services in the US are fed from a single phase step down transformer. The output secondary winding is called a Split Phase Winding. The single phase 240V winding has a center tap in the middle of the winding. The center tap leg is called the neutral. When connected to mother earth it becomes the Grounded Conductor. The output voltage of the split phase winding is 120/240Vac or 240/120Vac, nominal. Two Hot Ungrounded conductors and one Grounded conductor will feed the electrical service of the residential dwelling.

How does a 120/240V single phase split phase winding work?
Here is a good video on how it works.

Your problem if you plan on feeding your 230V audio equipment from the 240Vac mains power here the US, in the UK the 230V power has a neutral and a hot conductor + EGC (Equipment grounding Conductor). Here in the US the 240V mains are both Hot ungrounded conductors.
120V 0V 120V. The internal safety fusing for audio equipment is only on the Hot Line. The neutral Line is not fused. Which is correct when the equipment is fed from AC mains that use a neutral and hot conductor, as is the case in the UK and 120V mains here in the US. Not the case for US 240V mains power. Both  240V ungrounded Lines should be fused.
