Home Appliances Power
These are current measurements of my home lights and appliances. Measurement was using a clamp ammeter, as described in Comparing Tubular Fluorescents except that the higher currents and currents measured at the circuit-breaker box were measured without the ten turns adjustment. The table converts these to power consumption, assuming a power factor of 1 and supply voltage of 220V.
