One of the most critical safety aspects is the earthing system. Both SEWA and other UAE authorities emphasize robust earthing for all fixtures to ensure proper fault current flow and reduce the risk of electric shock. On-site inspections specifically check earthing and bonding for electrical safety. Poor earthing systems are a common reason for project rejections during the approval process.
Every earth electrode must terminate inside a dedicated concrete inspection pit with a removable cover to facilitate periodic testing.
