•
Not suitable if B is under 250 mm
•
No restrictions if B is greater than 1000 mm
If B is 300-1000 mm then the calculation is: A = B - 250
If B = 300
A = 300-250, the overhang can be 50 mm max.
If B = 350
A = 350-250, the overhang can be 100 mm max.
If B = 400
A = 400-250, the overhang can be 150 mm max.
If B = 450
A = 450-250, the overhang can be 200 mm max.
100 mm min.
If recessed with an overhang B =A+250
If A = 50
B = 50+250, clearance above needs to be 300 mm min.
If A = 100 B = 100+250, clearance above needs to be 350 mm min.
If A = 150 B = 150+250, clearance above needs to be 400 mm min.
If A = 200 B = 200+250, clearance above needs to be 450 mm min.
No restrictions if D is greater than 400 mm
If D is less than 400 mm, C = D+50
C = 50 +50, side overhang 100 mm max.
C = 100+50, side overhang 150 mm max.
C = 150+50, side overhang 200 mm max.
C = 200+50, side overhang 250 mm max.
50 mm min.
No restrictions if D is greater than 400 mm
D = C-50
150-50, side clearance must be 100 mm min.
200-50, side clearance must be 150 mm min.
250-50, side clearance must be 200 mm min.
300-50, side clearance must be 250 mm min.
350-50, side clearance must be 300 mm min.
400-50, side clearance must be 350 mm min.
Unrated materials, up to a max. of 20 °C
200 mm min
If recessed with an overhang B =A+250
No restrictions if D is greater than 400 mm
If D is less than 400, C = D
C = 50, side overhang 50 mm max.
C = 100, side overhang 100 mm max.
C = 150, side overhang 150 mm max.
C = 200, side overhang 200 mm max.
100 mm min.
No restrictions if D is greater than 400 mm
D = C
150, side clearance must be 150 mm min.
200, side clearance must be 200 mm min.
250, side clearance must be 250 mm min.
300, side clearance must be 300 mm min.
350, side clearance must be 350 mm min.
400, side clearance must be 400 mm min.
