A remote sample kit for an electrical equipment housing comprising a fluid-filled tank, a liquid sample port in fluid connection with the tank, electrical contacts extending from the tank, and an enclosure surrounding the liquid sample port and the electrical contacts, the remote sample kit comprising:

a drain connector configured to connect to the liquid sample port of the electrical equipment housing;

a remote sample port;

a sample line connecting the drain connector to the remote sample port; and

a remote housing containing the remote sample port and configured to attach to a wall of the electrical equipment housing.

2. The remote sample kit of claim 1 further comprising:

a remote gas port positioned within the remote housing;

a gas connector configured to connect to a gas port of the tank; and

a gas line connecting the remote gas port to the gas connector.

3. The remote sample kit of claim 2 further comprising an opening in the remote housing to allow access to the remote sample port through the wall of the electrical equipment housing.
