Is "motor shall be certified and suitable for Zone 1 classified area and be of Ex-d type fitted with Ex-e terminal box, certified as a unit" a requirement typical for West Africa water?

Consider motors above 1.5 MW (rating up to 13.8 kW) as Ex-p and not Ex-d type.

What about motors above 3.0 MW shaft power rating up to 11kV, may be of Ex-pe type, meaning motor being of the Ex-p type fitted with Ex-e terminal box, certified as a unit.

That requirement will certainly have a cost impact (increase).
