devices for surge protection
Hi, If I add a MOV type device in parallel to the shore power cord will it offer some down stream protection to my RV?

Suppose it represents line-to-neutral
Now we need another buss.
To earth ground. Another horizontal line BELOW the neutral buss
Three horizontal lines. Common buss wires.
The second string MOVs, TVSs, and (not shown) Gas Discharge Tubes
Need to be connected to LINE at top
JUMP over top the center neutral buss and connect to bottom buss. Earth ground.
MOV devices are naturally bi-directional, as are Gas Discharge Tube Devices.
But TVSs. Transient Voltage Suppressors MUST MUST MUST be specified a particular type: BI-DIRECTIONAL
If there is enough interest in this, I'll shop on eBay and post the seller links for the correct rated devices. REMEMBER minimum 4 devices except GDTs EACH buss. Four, L-N and four L-Ground 20 mm MOVs preferably 1500 watt TVSs. Six each would be better yet. Yes, fuses are vital for TVS circuit protection.
Apologies for no E=MC2 formulas or equations. I've seen enough aimed at novices to last five lifetimes. Should ONLY be used for defense if a calculation or component value is questioned or challenged by another forum member.
