When panel and service changes are made, without full rewiring, we have to use the branch wiring that is already existing.  We cannot get the area as "clean" as we would like too, without adding extensions to the wires, which increases the cost of the job. Also, when it is just the panel that is upgraded we are restricted by attaching to the existing service pipe from outside.
All work in the "After" pictures have passed an Electrical Safety Authority Inspection.

Sometimes it is just necessary to replace the fuses with breakers.  In some instances (to cut down on costs for the homeowners) we will add a new combination panel onto the existing Main switch without increasing the actual Service size.  If the homeowner wishes to increase the size of the service at a later time, half the job is already done.

Sometimes receptacles look new and therefore you might think they are grounded, but are really hooked up to ungrounded wiring.  This is where we must install a Ground Fault Circuit Interupteur (GFCI) type receptacle as allowed in the Ontario Electrical Code under rule 26-700(8).  Due to older style outlet boxes these GFCI receptacles are so deep they cannot fit in, so we have to use a box extender. The other option is to replace the receptacle box completely, sometimes causing plaster damage.  Most customers go with the extender.
