Re: Outdoor Lighting
Your question looks DIY but I see you are a utility power engineer so I will give you some info.
First Romex is a brand, to the NEC it is NM Cable which is not suitable for outdoor use.
UF Cable looks like NM but is suitable for outdoors.
MC Cable is generally an indoor product, it typically has a spiral metal armor.
There are specific ($$) types of MC for outdoor use.
