Will the two diode junction box withstand an EMP?
323881
I'm no EMP expert but I doubt it. The junction box is plastic and wires go into the junction box so if the EMP doesn't directly get the diodes, the wires will pick up the EMP pulse and take it into the diodes so not much hope. You have to have a complete metal cage around everything to protect it from an EMP pulse which pretty much defeats the function of a solar panel.

The receiver needs to have surge protection built in to it. We have blown 2 within a year in our house.

I don't think the electronics inside would hold up very well to the elements. It's too expensive to risk putting it in an environment that might cause it to fail.

Yes. They should protect all the circuits. Not sure you need a bar since they should trip if there is a strike.

As with all electronics, it could be harmed in an EMP attack. Any electronics can be protected by building a Faraday cage.Simply bubble wraps what you want to protect and put it in a metal tin like a popcorn tin.

The fuse block can handle the voltage, but the fuses will be up to you to find. This fuse box should be used indoors or in a protected area, not exposed directly to the elements.

The device is unlikely to be damaged. Conductors present in these devices are simply too short to intercept any significant amount of the EM pulse, and thus no spike is generated within them that is sufficient to cause damage.

not sure only tried it on my outside hook up but like i said both of them have just exploded so i am done good luck make sure you keep the box to send it back in and do not wait to long good luck

Yes. Absolutely, and if anyone wants to argue differently, I'll be happy to forward the pictures of my burnt out Bestek and the charred internal control board. Nothing but a laptop drawing current when this happened. If the manufacturer is reading this, experienced a control board fire in the vicinity of capacitors 2 & 14, and Diodes 6,7,8,9. Yes, my breaker tripped at the box, but not before the damage, and it was anything but overloaded. The fire literally shot out of the *grounding receptacle* (bursting capacitor maybe?), which burned a hole in my sleeve and another on my thumb. There's a good chance your fire insurance is invalidated by using non UL listed products -and as I discovered today, for good reason. I've permanently retired all three of mine and won't be looking back.

Yes, it needs to put in a junction box and keep away from insulation 3-4 inches.

Yes - If properly wired the opto-couplers protect the controller and data lines from the relay circuit.

Hell no. I would not trust it at all. I had 2 of them blow fuses and melt on me. They get hot as hell. There are better ones out there. DO NOT BUY!

These little boxes are worth the minimal cost, they'll indicate an emission from your power lines, TV, computer but didn't respond to my cell phone which is in the GHz range. They'll tell you where NOT to spend your time in an EMF like a plug under your bed or your laptop --on your lap!

Not sure how its shielded internally but I measured a very low EMF. Does not effect my equipment even when i am within inches of light fixture

I THINK so, Friend Sutherland... This unit SEEMS to have no built-in Loading Resistor Array (as my other one had) to overheat and raise the Stench Level. This unit clearly tests for UNLOADED PSU voltages; imho the price reflects that lightweight design. OTOH, searching the Web on the terms [ ATX Molex pinout ] will reliably reveal the Two Magic Pins that are momentarily connected to each other in order to to start the works whenever the Box's front-panel button is pressed from cold-start... One wee jumper, permanently bridging those two adjacent Molex pins, will Just Do the Job for No Money. That's what I do in MY lab whenever called-for. Hasn't ever failed me. Just doing what the test appliance does, is all! ;) And that is all. 0{;-)o[

It depends on what you actually want to check. If it is the actual shock then there might be an issue. I'm not an expert on electrical fences but they probably use a lot of high powered capacitance to achieve the shock and the voltage level might exceed the DMMs spec. I know the old weed burner fences put out a lot of high voltage. The other thing is that the more modern fences deliver pulses which are probable to fast for the device to measure (particularly on auto-ranging). Good luck but be careful!

we use 4 of these all over the house, each on a different circuit breaker and they work fine. I am unsure of what you mean by "2 electrical boxes".
