Seattle City Light has hired two companies to inspect the 20,000 metal streetlights and 10,000 ‘hand hole’ plates for contact voltage. They will be publishing (it appears) weekly status reports on their Power Lines blog. You can follow their progress here:
Once the initial inspections and surveys are complete, it is imperative that SCL schedule routine maintenance inspections on a regular schedule, and document these inspections, as well as acceptance procedures for new installations of streetlights. After all, deterioration does occur.
Contact voltage is not unique to streetlights, as the latest finding in downtown Seattle exhibited. The voltage had ‘leaked’ to a mailbox, bike rack, etc., energizing many surfaces.
We need to protect our loved ones from this danger.
