Adding surge protectors won't make anything pop - unless you simply plug too much stuff into them, and overload the circuit. However, you gain little surge stopping power by daisy chaining. You may also compromise safety: too many extension cords daisy chained can lead to excessive impedance, which means a short circuit might not trip a breaker (resulting in a fire), or a ground fault may not trip a breaker, leaving dangerous voltages on the chassis of an appliance.

As many as you like! Think about it. You've got a surge protector rated for (say) 2,000 watts. You can then plug a bunch of those into another surge protector...does that change the rating? NO! So not you have 16,000 watts of power available. Now just plug in even more surge protectors, 128,000 watts available...and so on, and so forth. Now here's the secret: Take the bottom surge protector, that everything is plugged into, and plug it into the top surge protector. Since the bottom surge protector is now supplying 128,000 watts, but only consumes 2,000 from the top, you get unlimited free energy.

A quick guess would be that you could keep daisy chaining them until you hit the chandrasekhar limit, after that they would go boom. So, based on some quick number crunching (and a guess on the average mass of a surge protector) you should be able to daisy chain 1.108X10^32 surge protectors before they go boom.

I'm surprised more people don't know about this. I've been running my house on free energy for years.

The fear is if you exceed the watt (or VA?) rating of the thing. Lot easier to do it with 24+ sockets than 8 -- retards out there.

Damn knew I should have paid more attention in that Intro to EE course I took for fun (with all the EECS people @ Cal) back in uni. Shows that you can get an A in something and still haven't learn it. Let see now. V = IR P = I^2 R, given that power will be constant to run things. R rises through series but decreases through parallel. So if a circuit is being run parallel, then I would have to increase by the squareroot of the drop in R to keep P constant. Meaning more heat. I'm not sure if surge protectors are in series or parallel. Most likely a combination with the series part protecting the parallel part. So short answer: Until it gets too hot @ the originating surge protector. Did I get it right?

Remember 1500watts per CIRCUIT or you will trip the fuse> overpower the circuit. How many protectors you daisy chain doesn't make a difference.

Most residential grade surge protectors are simply a MOV across the input and a few chokes. If you daisy chain surge protectors, you are effectively putting them all in parallel. It will actually improve performance some, but will definitely improve longevity (number of hits). It won't make anything go boom.

I had to google for the current accepted value - it's on the order of 10^30 kg. So, props for mentioning the chandrasekhar limit, but 38 surge protectors per kg? That's less than 1 ounce each!
