I can't find them anywhere....

left one is a complete pyramid. right one is just the foundations.

sorry. left looks like some type of luminaire. dunno about the other one.

So if a guru like you doesn't know what they are...how am i expected to know them for my coursework!

I think they come from BS EN 60317 and are part of the electrical symbols used on installation drawings
From memory they appear to be
RHS = double pole main isolator
LHS = Contactor or distribution Board

I would expect a drawing to come complete with a key to the symbols used on it.

On second thoughts
LHS = Distribution board / CCU
A square with a Saint Georges cross = contactor
