I'm in WA state. PoCo is Mason PUD #1. AHJ is WA L&I. I recently had my first inspection after upgrading meter box from 200A service to 400A service. Only flunked for 7 things. One of them was "add guy kit on service mast". The roof is metal. Inspector said since the mast is more than 2' above the roof (I wanted separation between service wires and metal roof. It's probably 3-3 1/2') and is a 3" mast and will have heavy wires attached, it needs a guy wire (or wires?).
I'm picking up an MK-3 from Platt: https://www.platt.com/platt-electric-supply/Mast-Guying-Kits-w-Wire/Nichols/MK-3/product.aspx?zpid=43927. I suspect it won't come with directions. I'm wondering if someone can provide guidance on how to install it. E.g., how high up should the wires be attached to the mast? What directions should the wires head away from the mast? Is there a distance away from mast or angle down I should aim for when determining where the roof attachments go?
I've attached a picture of the mast. If it'll help, I can get a better shot next time I'm on site (if the rain lets me). The power pole is currently about 15' beyond the right end of the house and about 10' in front of the front of the roof line. With that said, though, I hesitate to add guy wires based on that. PoCo wants to upgrade service wires in the neighborhood. They may move the pole elsewhere. They may even go underground (in which case, at some point, this all becomes moot). But, I should probably add the guy wires that make sense now, and worry about the future when it happens.
