What causes this? Multiple things, but the most common is when you plug your shore cord into a campground receptacle (or even at home), and you do NOT turn off the breaker first. Have you ever seen that small spark when plugging something in?

Look at this: DeoxIT D5 just a small squirt will help keep your prongs from ending up like that. More shore cord maintenance can be found here: Shore Cord Maintenance
