Abstract

An electricity conducting cord has first and second ends, one of the ends comprising an electrical connection member engageable with a power connection member of an apparatus having an apparatus power rating, at least one of the power connection member and the electrical connection member comprising electrical connectors and a physical cord identification member, the physical cord identification member is configured to inhibit the electricity conducting cord being electrically connected to the power connection member if the electricity conducting cord has a power rating lower than the apparatus power rating.

Claims

1. An appliance having an appliance power rating the appliance comprising

(a) an electrically operated member;

(b) an electrical connection member having a first face; and

,

(c) an electricity conducting cord selectable from a plurality of available electricity conducting cords of varying gauges, the electricity conducting cord having a first end connectable in electric communication with the electrical connection member and a second end connectable with a source of electricity, the first end having a second face

wherein one of the first and second faces is provided with male electrical connection members and the other of the first and second faces is provided with mating female electrical connection members

wherein the electrical connection member has a first cord identification member and the first end of the electricity conducting cord has a second cord identification member, one of the first and second cord identification members comprises a male cord identification member and the other of the first and second cord identification members comprises a female cord identification member and

(i) the male cord identification member increases in size as the gauge of the electricity conducting cord increases, or

(ii) the female cord identification member decreases in size as the gauge of the electricity conducting cord increases.

2. The appliance of claim 1 wherein the first and second cord identification members are inter-engageable only if the electricity conducting cord has a power rating the same as or higher than the appliance power rating.

3. The appliance of claim 1 wherein the cord identification member of the electricity conducting cord is positioned or configured based on the length and gauge of the electricity conducting cord.

4. The appliance of claim 1 wherein the electrical connection member is a plug and the first end of an electricity conducting cord is a socket.

5. The appliance of claim 1 wherein the electrical connection member is a socket and the first end of an electricity conducting cord is a plug.

6. The appliance of claim 1 wherein at least one of the electricity conducting cord and the electrical connection member includes a fuse.

7. An electricity conducting cord selectable from a plurality of available electricity conducting cords of varying gauges, the electricity conducting cord having first and second ends, one of the ends comprising an electrical connection member engageable with a power connection member of an apparatus having an apparatus power rating, the electrical connection member comprising a face having electrical connectors engageable with mating electrical connectors provided on the power connection member and also having a first physical cord identification member engageable with a second physical cord identification member provided on the power connection member,

wherein the electrical connection member has a first cord identification member and the first end of the electricity conducting cord has a second cord identification member, one of the first and second cord identification members comprises a male cord identification member and the other of the first and second cord identification members comprises a female cord identification member and

(i) the male cord identification member increases in size as the gauge of the electricity conducting cord increases, or

(ii) the female cord identification member decreases in size as the gauge of the electricity conducting cord increases.

8. The electricity conducting cord of claim 7 wherein the first and second cord identification members are inter-engageable only if the electricity conducting cord has a power rating the same as or higher than the apparatus power rating.
