Abstract: The invention relates to a heating system (100, 100-2) comprising: i) at least one resistive heat element (10, 18); ii) at least two terminals (T1, T2) for receiving a grid voltage (Vg) from a power grid, and iii) a controller (50) for being connected to the terminals (T1, T2) for receiving the grid voltage (Vg), the controller (50) connected to the at least one resistive heat element (10, 18) and being configured for controlling a load current (I_RT) through the at least one resistive heat element (10, 18), wherein the controller (50) is con-figured controlling the load current (I_RT) though the at least one resistive heat element (10, 18). The controller (50) comprises an FCFO-bidirectional power switch (58, 58-2, BPS) connected in series with the at least one resistive element (10, 18) for controlling the load current (I_RT) that is received from the power grid. The invention also relates to a method of controlling the load current (I_RT) through the at least one resistive element (10, 18), which applies a certain algorithm to avoid inrush currents, shorten the length of a cold-start and solve problems such as EMI.

Abstract: A junction box (1) for connection of electrical cables comprising a primary wall unit (10) and a secondary wall unit (12) configured removably connectable with each other and configured to bear against each other at a first connecting portion (30) of the primary wall unit and a second connecting portion (32) of the secondary wall unit, and sealing member (35) between the first connecting portion and second connecting portion. The primary wall unit comprise a first primary wall section (20a) and a second primary wall section (20b) as a unit, and the secondary wall unit comprise a first secondary wall section (22a) and three second secondary walls sections (22b) as a unit. The first connecting portion comprises a first ta-pered rim (40) and the second connecting portion comprises a second tapered rim (42) that is tapered correspondingly to fit with the first tapered rim (40).
