Only true if the receptacle and lamp are wired correctly. Really a non-issue as no sane person will stick their finger into the bulb socket.

That part is completely accurate. But fuses never protect appliances.

A surge is a microsecond event that can also blow through a tripped fuse. Fuses take milliseconds or seconds to trip. Multiple surges have long ago done damage before a fuse can even think about tripping.

A fuse is to protect human live (ie from fire) AFTER appliance damage has occurred; due to a surge, or due to a more common reason for failure - manufacturing defects.

Human safety is never about sanity. Humans are so innovative because humans constantly make mistakes. Human safety is about protection even the sanest person from his mistakes. Just another reason why AC electricity has so many redundant protections. Polarity is simply one of so many protections for humans.

BTW, that is why more responsible humans always use a parking brake as well as put the transmission in park. And why responsible humans do not race up to red lights and then heavily apply brakes. Every potential danger always requires additional protection layers.

Westom, I guess the older folks (me)were just lucky we lived without all the regulations, etc. Went bare footed, drank from rubber hoses, rode in pickup beds, rode bicycles without 40# of protective gear, played on gravel school yards, ate home prepared sack lunches at school, etc.

Nowadays, we have to have "Big Brother" protect us against everything including ourselves.

And we're still here to talk about it. It was much more fun "in the day".

Kids can no longer walk the quarter mile from bus to home. The bus stop is chocked with SUVs waiting for them. In 5th grade, we would take trains into NYC or Chicago for the day - just us - no parents.

Safety is one thing. Fear created by ignorance is another. To many replace knowledge (logical thought) with fear (emotions).

From post #1:

There has been a lot of educational info passed along here. Taranwanderer, The choice will be yours. Many people camped for years before surge protection and never had many bad experiences. Maybe a shock when touching metal on a wall or door. I, for one, know that there are consequences to appliances and such that I won't do it. There are other campsites or other campgrounds that I can go to and plug into safely.

Taranwanderer, I hope you got your question answered.
