For this reason, pools, spas and hot tubs, have very specific electrical requirements. 1. Contact a Licensed Electrical. Follow the principle of "right cord, right place, and right use" when using extension cords outdoors. Stop. Look. Live. Stay safe around powerlines. Always stay 3 metres away from overhead powerlines and at least 10 metres (about the length of a school bus).
