NOTE: The upgrade has been done because the "old" slide-on connectors often suffered meltdowns as a result of transitional resistance and the following heatdevelopement caused by improper wiring or currents going over the maximum rating for the connectors. | NOTE: The upgrade has been done because the "old" slide-on connectors often suffered meltdowns as a result of transitional resistance and the following heatdevelopement caused by improper wiring or currents going over the maximum rating for the connectors. |
