Rules for vertical clearances for telephone, cable TV, internet, and other data lines varies considerably from community to community, but the NESC sets forth these guidelines:
For data wires over pedestrian traffic: a minimum vertical clearance of 9 1/2 feet For data wires over vehicle traffic: a minimum vertical clearance of 15 1/2 feet For data wires over a pool or hot tub: a minimum vertical clearance of 10 feet
Also, there should be 30 inches of clearance between communication lines and electrical service lines.
昨天检查一个出租房,发现外面的electric box掉下来了,上面的柱子也歪了。原来是1个月前有一大卡车从门前经过,把租客的cable线给挂住了(cable和电线都是从路对面的电线杆扯过来的),但cable公司(Comcast)因为cable太低,把cable线绑在了电线上(电线比cable高),所以电线也给拉走了,听说电线被拉了很远。造成了电线盒和上面的柱子分离。打电话给电力公司,来的电工说他们不负责修。他们只负责电线和meter,box和柱子都是房主负责。他说可以给我们修,因为他私下接活。报价$900。包括换box和复位柱子。觉得挺贵,就找了我们熟知的一个电工,我们自己去买材料,我和老公帮他一起修。这样最后花的并不多,但费时费力,昨天一下午,今天又7点到12点,lowe's都跑了3趟。修的过程中,和租客谈,租客说应该卡车司机负责,但卡车司机不知去向。所以应该找Comcast负责,因为若cable不绑在电线上,电线也不会受影响。盒子和柱子也不会坏。现在也只能找Comcast了,司机是找不到的。我们本来想就这样了,我们就付了得了,但觉得租客说的也有道理,请大家帮忙分析一下,我们已经修好了,找Comcast怎么赔呢?
are you sure the pole is yours?
关键是你要查过街线应该至少多高(clearance height),cable线有没有低于那个高度。一辆卡车再高一般也不会平白无故拉到电线吧?
所以我觉得即使找到卡车,他们也不一定赔;最终原因可能是cable拉得太低。
你要是去comcast索赔的理由是他们拉线太低,而不是捆绑在电线上,因为捆绑在电线上可能是common practice。

但至少我们这儿貌似cable是不可以挂在weatherhead mast上的,需要单独走
我们那个没坏,是柱子下面和电表盒子链接的地方坏了,还有就是装电表的盒子坏了。cable是绑在半空中(路上空)绑在了电线上。没有帮到weather mast上。
