家里大功率电器启动时，一般灯会闪烁一下，这个可以理解，但是现在会导致某些电器
自动重启，例如电脑，电子钟什么的，感觉是电压掉了一段时间。
这个一般是什么原因造成的？

那应该是铜的，老房子都铜线，就六十年代忽然铝了几年又改回去了
铝线据说热胀冷缩厉害，会有你说的现象
你这情况看起来更像是electric panel太古老了

这情况建议从室外先检查，打电话去电力公司，先请他们去检查变压器和电表，确定没
事后再开始检查室内的。变压器和电表是属于电力公司的，免费检查的。

I had an electrician come over, he found out that my neutral in actually
connected to the ground, now my ground connection is going flaky.

Neutral wire is connected to the ground, which is how circuit breaker panel
has been wired. Large panels have 2 bars in different places, however there
is a bonding strap which connects them together through the panel.
One bar

it was in the main panel
the neutral is connected to the screw where the ground wire (which connects
to a spike in the ground) is hooked to.
I googled, it seems that that should be done in the subpanel?

I looked it again and I believe I was wrong.
I think it was one of the "legs" connected to the ground.
e.g. the black wires from meter,
basically in the pictures below, one "hot" wire was connected the ground,
the electrician didn't know how it could be working for so long.
