How do I determine if a wire is large enough to handle an additional electrical load?
First you must determine the electrical requirements of the load. The information you must have is voltage, amperage and whether it is single phase or 3 phase (most household wiring is single phase).
There are various sources of information to match the required load to the proper wire size but the easiest way is to ask a qualified electrician.
