Receptacle Safety Instructions for 240V Plug-Type EVSE
An EV Supply Equipment (EVSE) draws substantially more power
than any average home load. As a result, it is crucial to select an ap-
propriate receptacle that can support these products. A suitable 14-50R
or 6-50R receptacle is supplied with, and must be used with your plug
type EVSE. Improper selection of receptacles at the installation site
puts the EVSE at risk of overheating and may result in a fire hazard.
A simple way to ensure your receptacle model will be a good fit for
the EVSE is to check the metal contacts visible on the front face. It is
strongly recommended to select a high-quality industrial grade outlet
that has two full contacts in both receptacle slots.
As can be seen in Figures 1 & 4 above, a good receptacle has a contact
surface area that occupies the entire slot and makes full contact with the
blade of the plug. In contrast Figures 2 & 5 show how bad receptacles
have contacts that occupy only half the slot. Figures 3 & 6 are provided
to demonstrate the contact that would be made as the NEMA plugs are
inserted into the respective receptacles.
It is also highly recommended that a qualified electrician inspects the
premise wire connections on the back of a pre-existing NEMA out-
let before using it. Wire connection points behind the receptacle may
become loose or oxidized if they were installed many years ago and
may cause the outlet to fail. Ensure that the receptacles are free of any
physical damage or defects prior to the installation of the EVSE.
