Modular conduit-bridging ramp and couplings for electrical conduits

An electrical coupling comprising:

• a housing having a cavity;
• a plug or socket connector fixed to the housing;
• an electrical conduit connected to the plug or socket connector;
• an electrical current sensor in the cavity for sensing current flowing in the conduit;
• a control circuit in the cavity electrically connected to the current sensor;
• and
• a plurality of light emitters mounted in the cavity, each light emitter being electrically connected to the control circuit, each light emitter directing light through a respective window in the housing, the windows being substantially aligned, whereby the control circuit actuates the light emitters to provide a visual indication of the current sensed in the conduit.

An electrical coupling system comprising:

• male and female couplers joined by a push-turn action, each coupler having an axis, the male and female couplers having respective first and second abutment faces lying in radially aligned planes, a peripheral recess about each abutment face, and a resilient annular seal in each recess, wherein
• the male coupler has a plurality of male coupler electrical contacts protruding in an axial direction from the first abutment face, each male coupler contact having a radially protruding shoulder, and
• the female coupler, has cavities in the second abutment face for receiving each of the male coupler contacts in the axial direction, female coupler electrical contacts in each cavity engaging each shoulder upon relative rotation between the male and female couplers to mechanically connect the male and female couplers, to each other;
• and
• a collar for connection between the male and female couplers the collar being received in the recess in each male and female coupler, the collar having two opposing annular faces for contacting and compressing the seals on the male and female couplers, thereby urging the male and female connections, when mechanically connected apart.
