New 200 A Service on Vintage Home in Hyde Park
Posted on July 16, 2014 at 8:55 AM |
Out with the old and in with the new!
We upgraded the service on this vintage home on Woodlawn Ave recently.
Notice how the old white metal box which contains the original meter was
only fed with a small cable? While that was adequate for 75
years ago, it falls way short today. The 2" rigid pipe that goes up
contains the large power cables for the new 200 Amp service. Also
notice the small 1/2" pipe that comes from the bottom of the meter
housing and goes down to the sidewalk. This provides the supplemental
grounding cable, which is bonded to an 8' driven copper ground rod. The
Chicago Electrical code now calls for a more robust main ground and a
supplemental grounding system on every service. This is very necessary
for fire safety and protection from severe over voltages. |
