1 E 2 Underground bare ground is preferable for greater ground contact. In cables or boxes the controversial idea seems to be that an intrusion or fault may hit a bare conductor faster leading to a breaker trip. 3 Electric tank water heater: Non-professionally installed and not to the building code. Code issues observed include (1) pressure relief valve pipe is too small (2) pressure relief valve pipe does not drain which is only allowed in certain circumstances not present here (3) missing insulation on pipes. (4) for earthquake states flex line is required (4) power cable is unlikely to be listed for this application. Recommend professional work to make safe and to code. 4 B “if properly marked” 5 Terminals show signs of heat stress and rust. Recommend urgent evaluation and repair by a qualified electrical contractor. Extra credit: No Answer ---

1- d 2- heat resistance, high conductivity, and flexibility 3- electric water heater, TPR is downsized and not properly routed, it is possible the flex line outlet may not meet AHJ requirements, unable (from this photo) to determine proper power source and supply. Consult a proper qualified plumber/repair person to make corrections as required by local code. 4- b, but more info in question is needed. 5- SAFETY. The conductors in photo show signs of rust and possible overheating at some point. It is also observed there is contaminate, in the form of paint overspray, in the enclosure. Consult a qualified electrician to make repairs as needed. EC- John Mayall- I Cant Complain ---

The red tips are a rare find! As are the ones wrapped in paper with corn starch you can puff out “smoke”. Maybe those were the gum type though. Memories! ---
