Caravan/RV: If you have connected your RV/caravan’s 15A circuit to your home without using an Ampfibian or a designated 15A power point and overload the circuit, it may cause a fire. As it is illegal to directly connect a 15A caravan/RV to a 10A domestic socket, it will also invalidate your insurance.
Work-site: Using an illegally modified lead to connect a 15A welder, grinder, cutter or drill to a site’s 10A supply can cause damage and delays. Use of illegal equipment invalidates insurance cover and will lead to immediate ejection from the site when discovered. Don’t risk it.
