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?

Nah, they're 200V 14mm MOVs. I couldn't resist. The distance/reaction time of the TVS (
Placement of the board may be significant. Entry or service drop is ideal. But then I have some 5K Joule devices :) I would be a sucker for 20K watt TVSs but oh what the heck - I still have most of a pallet left of isolation transformers.
For an RV I would advise 2X MOVs and 2X TVSs. Single GST is sufficient. Encourage lightning to establish a route of ionization as far away as possible given the tight quarters of an RV.
Coincidence. Jesús told me this morning my lightning suppressor sustained a direct hit via the X1, X2, X3, L0 distribution network which is a couple of Km in length. The area single phase distribution network. The hit vaporized the service drop, 6 AWG wires, jumped the bait gap (1/8") to the diversion and vaporized the 6 gauge drain cable and most of the 1/2" grounding rod. I'm trying to get WhatsApp images and will post. Thank god for 14" dual-pole lever throw switches. Open circuit that is. Saved a lot of house wiring. Appliances were all unplugged while I'm gone. Apparently the strike occurred within 30 meters of my service drop. Blew the meter into shards. Siemen's breaker and meter base looks like a grenade hit it, says my son-in-law. Massive grid appliance damage.
