When necessary to probe live circuits, always keep ______________ behind your back.

Keeping one hand behind your back while probing live circuits is a critical safety practice. This technique reduces the risk of electrical shock. When both hands are in contact with live circuits or components, there is a potential for current to pass through the body from one hand to the other, which can cause serious injury or death. By using only one hand to manipulate the probe and keeping the other hand back, you minimize the path that electrical current can take through your body.

This practice is especially important in the context of working with RV electrical systems, where voltages and currents can be hazardous. Keeping one hand behind your back helps maintain focus and safety, ensuring that you do not inadvertently touch another conductive surface while working on a live circuit.
