The electrical work per unit of charge, when moving a negligible test charge between two points, is defined as the voltage between those points. The work can be done by electrochemical devices (electrochemical cells) or different metals junctions generating an electromotive force.

For electrical energy to move electrons and produce a flow of current around a circuit, work must be done, that is the electrons must move by some distance through a wire or conductor. The work done is stored in the flow of electrons as energy. Thus “Work” is the name we give to the process of energy.

However, the electric should always come after the plumbing. In fact, much of the actual work for the electricity won't happen until later anyway. You can't run electrical line in a home that's not dried in. Contractors will have to come back several times to finish what they start

Frequent electrical surges. Electrical surges can be caused by anything from lightning strikes, damage to power lines, faulty appliances and bad electrical wiring in the house. ... If you experience frequent electrical surges, the culprit is probably an electrical device connected to the home grid or the wiring itself.
