A 2-inch conduit can hold a wire for 200 amp service, 100 amp service enters in a 1 1/4-inch conduit and a 1-inch conduit holds a wire for a 60 amp service. Many conduits are oversized, so it's possible to have a 60 amp service entering your house in a 2-inch conduit.
The two main types of fog. Most common over land is Radiation Fog which occurs on clear nights with light winds. Radiation from the ground escapes out to space, the ground cools and, in turn, cools the air in contact with it. On an absolutely still night, condensation will occur on the ground to form dew. With slight air movement, sufficient condensation forms on condensation nuclei to form very small droplets of water - mist or fog. If the wind increases or a layer of cloud comes over, then the fog is likely to clear.
This is the cause of the whitish vale that we all know. The term fog is used when visibility reduces to less than 1km and the relative humidity exceeds 95%. Whereas mist is reported when visibility exceeds 1km. Obscuration by dry particles is defined as haze , which must not be mixed up with the popular, but somewhat vague term 'hazy skies' describing high thin clouds (often cirrus) obscuring the sun. Another form of fog is sea, lake or river smoke.
